Project: Hadoop
Issue Type: Bug

Environment: hadoop snv 612165

I am getting compaction errors from regions after they split not all of them
have this problem but some do
I attached a log I picked out one region
webdata,com.technorati/tag/potiron:http,1200430376177
it is loaded then splits at
2008-01-15 14:52:56,116
the split is finshed at
2008-01-15 14:53:01,653
the first compaction for the new top half region starts at
2008-01-15 14:54:07,612 - webdata,com.technorati/tag/potiron:http,1200430376177
and ends successful at
2008-01-15 14:54:30,229
ten the next compaction starts at
2008-01-15 14:56:16,315
This one ends with an error at
2008-01-15 14:56:40,246
{code}

{code}
and all other compaction's for this region fail after this one fail with the
same error I will have to keep testing to see if it ever finishes successfully.
maybe after a restart it will successfully finsh a compaction.
