Yongtao Yang created HDFS-9641: ---------------------------------- 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
