--------------------------------
Here was the stack trace for BucketAllocatorException bubbling out of the run()
method:
{code}

> Key: HBASE-11551
> URL: https://issues.apache.org/jira/browse/HBASE-11551
> Project: HBase
> Issue Type: Bug
> Reporter: Ted Yu
> Assignee: Ted Yu
> Fix For: 0.99.0, 2.0.0
>
> Attachments: 11551-v1.txt
>
>
> Currently the catch is outside the while loop:
> {code}
> try {
> while (cacheEnabled && writerEnabled) {
> ...
> } catch (Throwable t) {
> LOG.warn("Failed doing drain", t);
> }
> {code}
> When exception (e.g. BucketAllocatorException) is thrown, run() method would
> terminate, silently.
