    Description

      We are testing erasure coding with HBase. But we faced that the size of direct memory of HBase RegionServer keep growing.

      It is caused by that the direct memory allocated by ElasticByteBufferPool of HDFS client is never released.

      https://issues.apache.org/jira/browse/HADOOP-18105
      We found that we already have the solution, WeakReferencedElasticByteBufferPool.

      Just replace ElasticByteBufferPool with WeakReferencedElasticByteBufferPool.
