-----------------------------------
Summary: 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
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.
