Ability to do savenamespace without being in safemode
-----------------------------------------------------
Key: HDFS-1508
URL: https://issues.apache.org/jira/browse/HDFS-1508
Project: Hadoop HDFS
Issue Type: Improvement
Reporter: dhruba borthakur
Assignee: dhruba borthakur
In the current code, the administrator can run savenamespace only after putting
the namenode in safemode. This means that applications that are writing to HDFS
encounters errors because the NN is in safemode. We would like to allow
saveNamespace even when the namenode is not in safemode.
The savenamespace command already acquires the FSNamesystem writelock. There is
no need to require that the namenode is in safemode too.
