Subject [jira] [Commented] (HBASE-10867) TestRegionPlacement#testRegionPlacement occasionally fails
Date Tue, 01 Apr 2014 16:43:15 GMT

    [ https://issues.apache.org/jira/browse/HBASE-10867?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13956731#comment-13956731
] 

stack commented on HBASE-10867:
-------------------------------

bq. In 0.98 and prior releases, servers[] is of size 10.

I don't follow.  I see servers set to 10 in all versions.

In 0.98:

  private final static int SLAVES = 10;
...

    TEST_UTIL.startMiniCluster(SLAVES);

....


    ServerName servers[] = oldStatus.getServers().toArray(new ServerName[10]);
    ServerName serverToKill = null;
    int killIndex = 0;
    Random random = new Random(System.currentTimeMillis());
    ServerName metaServer = TEST_UTIL.getHBaseCluster().getServerHoldingMeta();
    LOG.debug("Server holding meta " + metaServer);
    boolean isNamespaceServer = false;
    do {
      // kill a random non-meta server carrying at least one region
      killIndex = random.nextInt(servers.length);

....


In trunk the same.

> So when 10 was used in TEST_UTIL.getHBaseCluster().getRegionServer(killIndex), we would
get ArrayIndexOutOfBoundsException.
