> MasterSchemaChangeTracker.excludeRegionServerForSchemaChanges leaks a
> MonitoredTask per call

> Key: HBASE-5702
> URL: https://issues.apache.org/jira/browse/HBASE-5702
> Project: HBase
> Issue Type: Bug
> Affects Versions: 0.94.0
> Reporter: Jean-Daniel Cryans
> Priority: Critical
>
> This bug is so easy to reproduce I'm wondering why it hasn't been reported
> yet. Stop any number of region servers on a 0.94/6 cluster and you'll see in
> the master interface one task per stopped region server saying the following:
> |Processing schema change exclusion for region server =
> sv4r27s44,62023,1333402175340|RUNNING (since 5sec ago)|No schema change in
> progress. Skipping exclusion for server = sv4r27s44,62023,1333402175340
> (since 5sec ago)|
> It's gonna stay there until the master cleans it:
> bq. WARN org.apache.hadoop.hbase.monitoring.TaskMonitor: Status Processing
> schema change exclusion for region server = sv4r27s44,62023,1333402175340:
> status=No schema change in progress. Skipping exclusion for server =
> sv4r27s44,62023,1333402175340, state=RUNNING, startTime=1333404636419,
> completionTime=-1 appears to have been leaked
> It's not clear to me why it's using a MonitoredTask in the first place.
