Kai Zheng resolved HDFS-8902. ----------------------------- Resolution: Duplicate > Uses ByteBuffer on heap or direct ByteBuffer according to used erasure coder > in striping read (position and stateful) > --------------------------------------------------------------------------------------------------------------------- > > Key: HDFS-8902 > URL: https://issues.apache.org/jira/browse/HDFS-8902 > Project: Hadoop HDFS > Issue Type: Sub-task > Reporter: Kai Zheng > Assignee: Kai Zheng > > We would choose ByteBuffer on heap or direct ByteBuffer according to used > erasure coder in striping read (position and stateful), for performance > consideration. Pure Java implemented coder favors on heap one, though native > coder likes more direct one, avoiding data copy. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
