--------------------------------
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.
