Kai Zheng created HDFS-8902: ------------------------------- Summary: 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)
