------------------------------------
Summary: HDFS Client's direct memory leaks with erasure codind
enabled
Key: HADOOP-19341
URL: https://issues.apache.org/jira/browse/HADOOP-19341
Project: Hadoop Common
Issue Type: Bug
Components: erasure-coding
Reporter: Eungsop Yoo
Attachments: image-2024-11-18-13-53-23-690.png
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.
