Subject [jira] [Updated] (HDFS-8804) Erasure Coding: use DirectBufferPool in DFSStripedInputStream for buffer allocation

Jing Zhao updated HDFS-8804:
----------------------------
    Attachment: HDFS-8804.001.patch

Thanks Nicholas for the review! Update the patch to address the comments. I did not add synchronized
to {{getParityBuffer}} because it is only used in StatefulStripeReader which is already protected
by the lock.

> 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.
