Sean Busbey updated HBASE-12655:
--------------------------------
Priority: Minor (was: Major)
> WALPerformanceEvaluation miscalculates append/sync statistics for multiple
> regions
> ----------------------------------------------------------------------------------
>
> Key: HBASE-12655
> URL: https://issues.apache.org/jira/browse/HBASE-12655
> Project: HBase
> Issue Type: Bug
> Components: wal
> Affects Versions: 0.99.2
> Reporter: Sean Busbey
> Assignee: Sean Busbey
> Priority: Minor
> Fix For: 1.0.0, 2.0.0
>
>
> Right now the WALPerformaceEvaluation tool sets up each new region by asking
> for a WAL and then adding a listener. The listener updates running stats on
> appends / syncs using a shared object in the evaluation tool.
> For WALProviders that reuse WALs (such as the default one always using a
> single WAL), this results in adding a listener to WALs that already have
> them. Each of those listeners is then updated on each append/sync.
