Wei-Chiu Chuang commented on HDFS-14892: ---------------------------------------- Good finding, Kihwal. I am aware the client creates an empty file in such a case but didn't realize the upstream leaks. > Close the output stream if createWrappedOutputStream() fails > ------------------------------------------------------------ > > Key: HDFS-14892 > URL: https://issues.apache.org/jira/browse/HDFS-14892 > Project: Hadoop HDFS > Issue Type: Bug > Reporter: Kihwal Lee > Priority: Major > > create() in an encryption zone is a two step process by the client. First, a > regular FSOutputStream is created and then it is wrapped with an encrypted > stream. When there is a system issue or a KMS ACL-based denial, the second > phase will fail. If the client terminates right away, the shutdown hook > closes the output stream opened in the first phase. But if the client lives > on, the output stream will leak. > Datanode's WebHdfsHandler, DFSClient, DistributedFileSystem, Hdfs > (FileContext) and RpcProgramNfs3 do this. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
