> Key: ACCUMULO-1352
> URL: https://issues.apache.org/jira/browse/ACCUMULO-1352
> Project: Accumulo
> Issue Type: Sub-task
> Components: master, tserver
> Affects Versions: 1.4.0
> Reporter: Keith Turner
> Fix For: 1.5.0, 1.4.4
>
>
> Comments and commits against the parent ticket (ACCUMULO-1044) address multiple causes. This substask summarizes one of those causes.
> Accumulo configure a filter on the metadata table that drops inactive bulk load flags. Inactive flags could be propagated by splitting tablets, and thats why this filter exist. There is a bug in the way the fitler works. It may delete active bulk load flags. If this occurs there is a small possibility that bulk loaded files could be moved. This would result in accumulo complaining about missing files.
> A work around for 1.4.0 - 1.4.3 is to remove this filter from the metdata table.
> {noformat}
> deleteiter -majc -n bulkLoadFilter -t !METADATA
> {noformat}
> Then periodically delete bulk load flags that are left by splits. Would need to add the filter back once this bug is fixed.
> All svn commits related to this issue were done using the parent ticket.
