Nick Dimiduk updated HBASE-10500:
---------------------------------
Attachment: HBASE-10500.01.patch
Patch moves conf management into constructors so that programatic use is also
corrected. Without it, IntegrationTestImportTsv and IntegrationTestBulkLoad
fail.
Also remove the apparently redundant config from LoadIncrementalHFiles. If you
were kind enough to provide a +1 earlier, note that this patch is a little more
invasive.
> Some tools OOM when BucketCache is enabled

> Running {{hbck --repair}} or {{LoadIncrementalHFiles}} when BucketCache is
> enabled in offheap mode can cause OOM. This is apparently because
> {{bin/hbase}} does not include $HBASE_REGIONSERVER_OPTS for these tools. This
> results in HRegion or HFileReaders initialized with a CacheConfig that
> doesn't have the necessary Direct Memory.
> Possible solutions include:
> - disable blockcache in the config used by hbck when running its repairs
> - include HBASE_REGIONSERVER_OPTS in the HBaseFSCK startup arguments
> I'm leaning toward the former because it's possible that hbck is run on a
> host with different hardware profile as the RS.
