----------------------------------
Summary: IOException in hdfs write process causes file leases not
released
Key: HDFS-9641
URL: https://issues.apache.org/jira/browse/HDFS-9641
Project: Hadoop HDFS
Issue Type: Bug
Components: hdfs-client
Affects Versions: 2.6.3, 2.6.2, 2.6.1, 2.6.0
Environment: hadoop 2.6.0,
Reporter: Yongtao Yang
when writing a file, an IOException may be raised in
DFSOutputStream.DataStreamer.run(), then 'streamerClosed' may be set to true,
then closeInternal() will be invoked, where DFSOutputStream.closed will be set
to be true. That is to say, 'closed' is true before DFSOutputStream.close() is
invoked, then dfsClient.endFileLease(fileId) will not be executed. The
references of the DFSOutputStream objects will still be hold in
DFSClient.filesBeingWritten untill the client quits. The related resources will
not be released. HDFS-4504 is a related issue.
