stack commented on HBASE-4553:
------------------------------
I ran test suite on local ubuntu and all passed except roll log; it had this:
{code}
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).
