>             Project: Hadoop HDFS
>          Issue Type: Bug
>          Components: ha, namenode
>    Affects Versions: 2.0.4-alpha

> 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.
