Guanghao Zhang commented on HBASE-21388:
----------------------------------------
The MemStoreLAB and ChunkCreator is global per process. The minicluster start
master and rs in same process, the ut will failed as rs will create a new
MemStoreLAB. Will find a way to resolve this later.
> No need to instantiate MemStoreLAB for master which not carry table
