[opensuse] Apache Hadoop and Java on openSUSE 12.1
by Roger Oberholtzer 10 Apr '12

10 Apr '12

I am messing around with Apache Hadoop. I have installed the 1.0.2 RPM on opeSUSE 12.1. I also have installed and enabled jdk-1.7.0_02-fcs.i586, which is Sun's release. When I run one of the commands for setting up Hadoop (as described on http://hadoop.apache.org/common/docs/current/single_node_setup.html), I get this: # hadoop jar /usr/share/hadoop/hadoop-examples-1.0.2.jar grep input output 'dfs[a-z.]+' java.lang.NoClassDefFoundError: org.apache.hadoop.security.UserGroupInformation at java.lang.Class.initializeClass(libgcj.so.12) at org.apache.hadoop.fs.FileSystem$Cache$Key.<init>(FileSystem.java:1494) at org.apache.hadoop.fs.FileSystem$Cache.get(FileSystem.java:1395) at org.apache.hadoop.fs.FileSystem.get(FileSystem.java:254) at org.apache.hadoop.fs.FileSystem.get(FileSystem.java:123) at org.apache.hadoop.examples.Grep.run(Grep.java:87) at org.apache.hadoop.util.ToolRunner.run(ToolRunner.java:65) at org.apache.hadoop.examples.Grep.main(Grep.java:93) at java.lang.reflect.Method.invoke(libgcj.so.12) at org.apache.hadoop.util.ProgramDriver$ProgramDescription.invoke(ProgramDriver.java:68) at org.apache.hadoop.util.ProgramDriver.driver(ProgramDriver.java:139) at org.apache.hadoop.examples.ExampleDriver.main(ExampleDriver.java:64) at java.lang.reflect.Method.invoke(libgcj.so.12) at org.apache.hadoop.util.RunJar.main(RunJar.java:156) I am curious why the error comes from libgcj.so.12, which is from libgcj46-4.6.2_20111026-1.1.2.i586, which is the GNU version. Does Sun's Java use anything from GNU's Java? I suspect that the problem is that some parts of my Java install are whatever openSUSE 12.2 installs, and part are from Sun. Is there a documented way to have only Sun's Java installled? Which includes removing the non-Sun components. It seems that most everything Java that I try works better (and sometimes only) with Sun's Java. And I also suspect that just installing and enabling Sun's Java may not be enough if ither non-Sun components are still around. Or perhaps I need more than Sun's JDK? -- Yours sincerely, Roger Oberholtzer OPQ Systems / Ramböll RST Office: Int +46 10-615 60 20 Mobile: Int +46 70-815 1696 roger.oberholtzer(a)ramboll.se ________________________________________ Ramböll Sverige AB Krukmakargatan 21 P.O.

[opensuse] zypper: sudo vs su
by Geza Giedke 10 Apr '12

10 Apr '12

Dear all, I used to run a script sudo zypper ref sudo zypper lu echo "ready" sudo zypper up to install updates; recently, that led to "permission denied" errors (see below) that could only be avoided by becomin root and then calling zypper. What is the reason? And isn't it generally recommended to use sudo instead of su? Thanks for your input. regards Geza The errors looked like: Retrieving repository 'openSUSE Current OSS' metadata [\] Permission to access ' http://download.opensuse.org/distribution/openSUSE-current/repo/oss/media.1…' denied. Abort, retry, ignore? [a/r/i/?] (a): a Retrieving repository 'openSUSE Current OSS' metadata [error] Repository 'openSUSE Current OSS' is invalid. [|] Valid metadata not found at specified URL(s) Please check if the URIs defined for this repository are pointing to a valid repository. Skipping repository 'openSUSE Current OSS' because of the above error. I removed the repositories and added them again, deleted the cache, did zypper clean etc, the error persisted (for all repositories); only when followin a suggestion in an old forum thread I became root and started zypper then, everything works fine again. -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse+owner(a)opensuse.org

The update RPMs for expat/libexpat/etc. announced in openSUSE-SU-2012:0423-1 disappeared from the update repositories last week. Were they withdrawn, or did something else happen? -- Kristofor A.

[opensuse] SSL Certificate question
by Jim Flanagan 10 Apr '12

10 Apr '12

This is probably a dumb question but here goes. A year ago I made a private key, and generated a csr for signing. Got a certificate good for one year. Question one. Is it technically possible to use that same private key to generate a new csr for signing again now? Question two. If so, is it advisable to use the same private key, or better to generate a new private key now? Many thanks, Jim F -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse+owner(a)opensuse.org

[opensuse] libreoffice crash and failed recovery
by George Olson 10 Apr '12

10 Apr '12

Hi Everyone, Hope you all had a happy Easter. I recently found that desktop effects was making my system unstable. It would cause my whole system to freeze up and become completely unresponsive. It happened when I would hit left-alt-tab to switch between open applications. This didn't happen all the time, but it did begin to happen frequently. So I disabled desktop effects and have since not had a crash (except once when using virtual box, but that is another story). In any case, I had an open libreoffice document when the system froze up, and I had just saved it. I reset my computer, and when it rebooted I went to open up libreoffice again. It started the recovery process, which had always worked before without a problem, but this time it failed to recover the file. I did end up losing that file and had to rebuild it from scratch. In any case, I don't have a need to recover that old file anymore. However, I still am having a small problem with libreoffice. Whenever I open up any document in libreoffice, it still tries to recover that old document and fails. You can see the screen shots below. http://picpaste.com/konquerorimg1-fc9tA0RU.jpg http://picpaste.com/konquerorimg2-zL9iwXW4.jpg So I am wondering, how do I get libreoffice to stop attempting recovery of this file? I don't need it anymore and it is kind of a pain in the neck now.

[opensuse] kde updates and yast taboo

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I'm using 11.4 and I updated my kde4 using http://download.opensuse.org/repositories/KDE:/Distro:/Stable/openSUSE_11.4/. Since them, yast online update wants to update dbus-1. yast2-control-center, and kdebase4-openSUSE, even though it means a vendor change, and even though I tabooed the changes. Everytime I open YOU, the 3 tabooes have disapeared. And I don't understand why not the vendor do not change rule doesn't take precedence over the updates YOU wants to do. Can I change that? - -- Cheers, Carlos -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.16 (GNU/Linux) iEYEARECAAYFAk+DRfoACgkQtTMYHG2NR9XvtACeMbB409kx4AqBwz/SheNZ5MV4 KQYAoI89m6MKzOpfih18lLg2hKnkrFSj =7+W+ -----END PGP SIGNATURE----- -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse+owner(a)opensuse.org

[opensuse] High interrupt rates (was about network interface overruns)

If you've followed the previous thread about network interface overruns, you will know that switching to a different network card didn't quite solve the problem, but it did significantly reduce the number of overruns. As Google suggested, it seems quite clear that the machine simply could not deal with the flow of interrupts, which was also evident in the slowing of the system clock! As far as I can tell, the clock was slowed down due to the system being unable to process the clock interrupt in a timely manner. Or is there another reason why the system clock would slow down during periods of many interrupts? Not just a few seconds, more than 1000s over e.g. 25-30mins. The question now remains - can this system be tuned/tweaked to process network interrupts better/faster? Any applicable kernel parameters? It is a dedicated firewall/router box with a PIII 800MHz and 512Mb RAM. The currently installed oS is 11.0 with kernel 2.6.25.5. -- Per Jessen, Zürich (10.1°C) -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse+owner(a)opensuse.org

[opensuse] OwnCloud, do I need to purchase a domain?
by Roger Luedecke 08 Apr '12

08 Apr '12

I wanted to set up OwnCloud for a client since it would fulfill his needs. He has a dedicated desktop system (running 11.4 that I set up) that sees only light use, and should be able to host OwnCloud. I am not terribly familiar with web technologies, and wonder if I would have to link it to an external domain somehow since it doesn't have a static IP. -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse+owner(a)opensuse.org
