> We are testing erasure coding with HBase. But we faced that the size of direct memory of HBase RegionServer keep growing. 
>  !image-2024-11-18-13-53-23-690.png! 
> 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.
