Subject [jira] [Commented] (YARN-449) HBase test failures when running against Hadoop 2
Date Wed, 13 Mar 2013 00:21:13 GMT

    [ https://issues.apache.org/jira/browse/YARN-449?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13600650#comment-13600650

Ted Yu commented on YARN-449:
-----------------------------

Here is sample content for /proc/<PID>/stat
{code}
30873 (sshd) S 30869 30869 30869 0 -1 4202816 360 0 0 0 47 56 0 0 20 0 1 0 741791881 117960704
516 18446744073709551615 1 1 0 0 0 0 0 4096 65536 18446744073709551615 0 0 17 2 0 0 0 0 0
{code}
Here is the regex used to parse the stat file:
{code}
  private static final Pattern PROCFS_STAT_FILE_FORMAT = Pattern .compile(
    "^([0-9-]+)\\s([^\\s]+)\\s[^\\s]\\s([0-9-]+)\\s([0-9-]+)\\s([0-9-]+)\\s" +
    "([0-9-]+\\s){7}([0-9]+)\\s([0-9]+)\\s([0-9-]+\\s){7}([0-9]+)\\s([0-9]+)" +
    "(\\s[0-9-]+){15}");
{code}

> Post YARN-429, unit tests for HBase continue to fail since the classpath for the MRAppMaster
is not being set correctly.
> Reverting YARN-129 may fix this, but I'm not sure that's the correct solution. My guess
is, as Alexandro pointed out in YARN-129, maven classloader magic is messing up java.class.path.
