--------------------------------------
bq.Just now, we haven't encountered such exception.
In our clusters, we have already do the same fix with the changes several
months ago, just think it has potential problem from code view.
So our clusters can't show this issue won't happen...
> BucketCache$WriterThread.run() doesn't handle exceptions correctly

> 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.
