Subject [jira] [Commented] (HBASE-6305) TestLocalHBaseCluster hangs with hadoop 2.0/0.23 builds.
Date Tue, 03 Jul 2012 13:27:20 GMT

    [ https://issues.apache.org/jira/browse/HBASE-6305?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13405914#comment-13405914
] 

Jonathan Hsieh commented on HBASE-6305:
---------------------------------------

Definitely has something to do with the attempt to auto set fs.defaultFS.  For 0.94, I got
it passing by removing these lines (note that fs.defaultFS == hbase.rootdir doesn't really
make sense I believe):

{code}

       // Get fs instance used by this RS
       this.fs = new HFileSystem(this.conf, this.useHBaseChecksum);
       this.rootDir = new Path(this.conf.get(HConstants.HBASE_DIR));
{code}

Unfortunately, this doesn't fix trunk -- it's error looks directly related to HBASE-6306.
