---------------------------------
Summary: after cluster failover, journalnode fails to come up when
space is freed, preventing namenode from coming up at proper state
Key: HDFS-11523
URL: https://issues.apache.org/jira/browse/HDFS-11523
Project: Hadoop HDFS
Issue Type: Bug
Affects Versions: 2.7.2
Environment: Ubuntu 12.04
Reporter: Sunil Iyer
after failover of a three node distributed cluster, one node with both namenode
and journalnode services was completely down. A second journalnode was in
wedged state due to insufficient space, so namenode service could not resume.
Once space was cleared however, journalnode did not resume on its own,
preventing a majority of journalnodes for namenode reads.
