-----------------------------------------------
@Deva
Am not able to tell clearly what is the problem. I too went thro those logs
and found that the region 5689a8785bbc9a8aa8e526cd7ef1542a has completed the
compaction.
{code}
2012-08-28 06:15:34,107 INFO
org.apache.hadoop.hbase.regionserver.compactions.CompactionRequest: completed
compaction:
regionName=TestLoadAndVerify_1346120615716,\xD8\x0D\x03\x00\x00\x00\x00\x00/000007_0,1346125261573.5689a8785bbc9a8aa8e526cd7ef1542a.,
storeName=f1, fileCount=3, fileSize=27.3m, priority=3, time=14360293782301;
duration=4sec
{code}
and later the split has started for the region (after 2 ms)
{code}
2012-08-28 06:15:34,109 INFO
org.apache.hadoop.hbase.regionserver.SplitTransaction: Starting split of region
TestLoadAndVerify_1346120615716,\xD8\x0D\x03\x00\x00\x00\x00\x00/000007_0,1346125261573.5689a8785bbc9a8aa8e526cd7ef1542a.
{code}
The offlining of the region is done here
{code}
2012-08-28 06:15:34,788 INFO org.apache.hadoop.hbase.catalog.MetaEditor:
Offlined parent region
TestLoadAndVerify_1346120615716,\xD8\x0D\x03\x00\x00\x00\x00\x00/000007_0,1346125261573.5689a8785bbc9a8aa8e526cd7ef1542a.
in META
{code}
So before this itself the region got closed. I feel the store file list should
have been updated by the time. No ?

> In our nightlies, we have seen RS aborts due to compaction and split racing.
> Original parent file gets deleted after the compaction, and hence, the
> daughters don't find the parent data file. The RS kills itself when this
> happens. Will attach a snippet of the relevant RS logs.
