Subject [jira] [Commented] (HBASE-4553) The update of .tableinfo is not atomic; we remove then rename
Date Fri, 04 Nov 2011 23:03:51 GMT

    [ https://issues.apache.org/jira/browse/HBASE-4553?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13144435#comment-13144435

stack commented on HBASE-4553:

I ran test suite on local ubuntu and all passed except roll log; it had this:


Tests in error: 
  testLogRollOnDatanodeDeath(org.apache.hadoop.hbase.regionserver.wal.TestLogRolling): Cannot
lock storage /export1/stack/hbase/target/test-data/74208e88-deaa-4d3c-a6ed-d316c5aa5ef2/dfscluster_0515d0e6-8fcd-47c0-8b34-9126722fc1cb/dfs/data/data3.
The directory is already locked.

which is unrelated.  Committing v13.

> This comes of HBASE-4547.  The rename in 0.20 hdfs fails if file exists already.  In
0.20+ its better but still 'some' issues if existing reader when file is renamed.  This issue
is about fixing this (though we depend on fix first being in hdfs).
