Keith Turner updated ACCUMULO-65:
---------------------------------
Affects Version/s: (was: 1.3.5)
(was: 1.4.0)
> missing minor compaction files under heavy namenode load
> --------------------------------------------------------
>
> Key: ACCUMULO-65
> URL: https://issues.apache.org/jira/browse/ACCUMULO-65
> Project: Accumulo
> Issue Type: Bug
> Components: tserver
> Environment: dynamic ingest on a large cluster, hadoop cdh3beta2
> Reporter: Eric Newton
> Assignee: Eric Newton
> Fix For: 1.3.5, 1.4.0
>
>
> Monitor was showing lots of errors for missing files. Analysis of any single
> file shows that the tablet was not moved, nor assigned to multiple servers.
> All the errors are for files that were minor compacted with many namenode
> operations failing/retried. The files were not deleted by the accumulo
> garbage collector. Checking the name node logs, there is no mention of the
> file being created, but there is a mention of the final rename of the file
> failing. Possible HDFS issue: file open and write succeeds, close succeeds,
> the file is then re-opened, and checked; yet the file is not created.
> The return code of the rename to bring the file online was not checked.
