> 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.
