> In our cluster, we use a small heap/offheap config for master. After 
> HBASE-21290, master doesn't instantiate BlockCache when it not carry table. 
> But it will new CacheConfig in SplitTableRegionProcedure.splitStoreFiles 
> method. And it will instantiate a new BlockCache if it not initialized before 
> and make master OOM.
