[jira] [Created] (HBASE-4978) Reduce offheap cache percentage in direct memory

Reduce offheap cache percentage in direct memory
------------------------------------------------

                 Key: HBASE-4978
                 URL: https://issues.apache.org/jira/browse/HBASE-4978
             Project: HBase
          Issue Type: Task
            Reporter: Zhihong Yu


Currently if -XX:MaxDirectMemorySize is given as JVM parameter, off heap cache would consume 95% of it.
We should leave enough room in direct memory for NIO.
