-------------------------------
Summary: Move IO operations out of locking in OpenFileCtx
Key: HDFS-4971
URL: https://issues.apache.org/jira/browse/HDFS-4971
Project: Hadoop HDFS
Issue Type: Sub-task
Reporter: Jing Zhao
Assignee: Jing Zhao
Currently some IO operations (such as writing data to HDFS and dumping to local
disk) in OpenFileCtx may hold a lock which can block processing incoming
writing requests. This jira aims to optimize OpenFileCtx and move the IO
operations out of the locking.
