-----------------------------------------
Summary: Provide an API for knowing that whether file is closed or
not.
Key: HDFS-4525
URL: https://issues.apache.org/jira/browse/HDFS-4525
Project: Hadoop HDFS
Issue Type: Sub-task
Components: namenode
Affects Versions: 2.0.3-alpha, 3.0.0
Reporter: Uma Maheswara Rao G
Currently recoverLease API will return true if file is already closed.
Otherwise it will trigger internalLease recovery and return false. It may take
some time to really complete this recovery and file to be closed completely.
So, there is noway for the users to wait correctly until file is closed
completely.
It would good if we have one API which says whether that file is closed or not.
So, that users can relay on that proceed further if and only if file is closed
completely.
