-----------------------------
Summary: CLONE - Erasure Coding: use DirectBufferPool in
DFSStripedInputStream for buffer allocation
Key: HDFS-10145
URL: https://issues.apache.org/jira/browse/HDFS-10145
Project: Hadoop HDFS
Issue Type: Sub-task
Reporter: dragon
Assignee: Jing Zhao
Fix For: HDFS-7285
Currently we directly allocate direct ByteBuffer in DFSStripedInputstream for
the stripe buffer and the buffers holding parity data. It's better to get
ByteBuffer from DirectBufferPool.
