Todd Lipcon created HDFS-3795: --------------------------------- Summary: QJM: validate journal dir at startup Key: HDFS-3795 URL: https://issues.apache.org/jira/browse/HDFS-3795 Project: Hadoop HDFS Issue Type: Sub-task Components: ha Affects Versions: QuorumJournalManager (HDFS-3077) Reporter: Todd Lipcon Assignee: Todd Lipcon Priority: Minor Attachments: hdfs-3795.txt
Currently, the JN does not validate the configured journal directory until it tries to write into it. This is counter-intuitive for users, since they would expect to find out about a misconfiguration at startup time, rather than on first access. Additionally, two testers accidentally configured the journal dir to be a URI, which the code accidentally understood as a relative path ({{CWD/file:/foo/bar}}. We should validate the config at startup to be an accessible absolute path. -- This message is automatically generated by JIRA.
