[jira] Resolved: (HDFS-1563) create(file, true) appears to be violating atomicity
[ https://issues.apache.org/jira/browse/HDFS-1563?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] dhruba borthakur resolved HDFS-1563. Resolution: Won't Fix I vote that we keep the semantics of the create(overwrite==true) the same as it is now. Please reopen this JIRA if you strongly feel otherwise. create(file, true) appears to be violating atomicity Key: HDFS-1563 URL: https://issues.apache.org/jira/browse/HDFS-1563 Project: Hadoop HDFS Issue Type: Bug Components: name-node Affects Versions: 0.20.1 Reporter: Guanghao Shen Assignee: dhruba borthakur Attachments: unittest.diff Will upload a unittest to reveal this bug. In a word, when a thread is doing create(file, true) on existing file, there are chances that another thread will get 'false' for exists(file) during the period. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
