             Summary: Master OOM when SplitTableRegionProcedure new CacheConfig and instantiate a new BlockCache
                 Key: HBASE-21498
                 URL: https://issues.apache.org/jira/browse/HBASE-21498
             Project: HBase
          Issue Type: Improvement
            Reporter: Guanghao Zhang
            Assignee: Guanghao Zhang


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.
