Keith Turner reassigned GORA-130:
---------------------------------
Assignee: Keith Turner
> gora-accumulo caches tablet locations between map reduce jobs
> --------------------------------------------------------------
>
> Key: GORA-130
> URL: https://issues.apache.org/jira/browse/GORA-130
> Project: Apache Gora
> Issue Type: Bug
> Components: storage-accumulo
> Affects Versions: 0.2
> Reporter: Keith Turner
> Assignee: Keith Turner
> Fix For: 0.3
>
>
> Enis added a new Loop program to goraci that continually runs Generation and
> Verification map reduce jobs. So you have one process launching multiple map
> reduce jobs. I was running this I noticed an issue. After the first round
> of generation, the table had 16 tablets. So verification ran with 16
> mappers, one per tablet. Then more data was inserted and the table split to
> 32 tablets. When verification ran again it started 16 mappers instead of 32.
> Turns out the gora-accumulo store was using stale cached information about
> the table to create the input splits for the map reduce job.
> This issues will not affect the simple usage pattern of a single java process
> launching one map reduce job that reads from accumulo.
