Subject [jira] [Created] (HDFS-4859) Add timeout in FileJournalManager
Date Tue, 28 May 2013 14:50:24 GMT
Kihwal Lee created HDFS-4859:
--------------------------------

             Summary: Add timeout in FileJournalManager
                 Key: HDFS-4859
                 URL: https://issues.apache.org/jira/browse/HDFS-4859
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: ha, namenode
    Affects Versions: 2.0.4-alpha
            Reporter: Kihwal Lee


Due to absence of explicit timeout in FileJournalManager, error conditions that incur long
delay (usually until driver timeout) can make namenode unresponsive for long time. This directly
affects NN's failure detection latency, which is critical in HA.
