Subject [jira] [Commented] (HBASE-4553) The update of .tableinfo is not atomic; we remove then rename
Date Sat, 08 Oct 2011 21:25:29 GMT

    [ https://issues.apache.org/jira/browse/HBASE-4553?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13123567#comment-13123567

stack commented on HBASE-4553:
------------------------------

So, I see this in this failure up on jenkins in https://builds.apache.org/job/HBase-0.92/53/artifact/trunk/target/surefire-reports/org.apache.hadoop.hbase.avro.TestAvroServer-output.txt

I see that we updated .tableinfo and a check on the files modtime at about the same time fails
with filenotfound.

Todd, should we spin here till file shows up?

> 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).
