>          Issue Type: Sub-task

>    Affects Versions: 1.4.0
>            Reporter: Keith Turner
>            Assignee: Eric Newton
>             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.
