----------------------------------
Summary: Change readChunk methods to return ByteBuffer
Key: HDDS-2261
URL: https://issues.apache.org/jira/browse/HDDS-2261
Project: Hadoop Distributed Data Store
Issue Type: Improvement
Reporter: Istvan Fajth
During refactoring to HDDS-2233 I realized the following:
KeyValueHandler.handleReadChunk and handleGetSmallFile methods are using
ChunkManager.readChunk, which returns a byte[], but then both of them (the only
usage points) converts the returning byte[] to a ByteBuffer, and then to a
ByteString.
ChunkManagerImpl on the other hand in readChunk utilizes ChunkUtils.readChunk,
which in order to conform the return value converts a ByteBuffer back to a
byte[].
I open this JIRA to change the internal logic to fully rely on ByteBuffers
instead of converting from ByteBuffer to byte[] then to ByteBuffer again.
