> 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.
