I have seen it. > Name Node should not process format command while it is running. > ---------------------------------------------------------------- > > Key: HDFS-1690 > URL: https://issues.apache.org/jira/browse/HDFS-1690 > Project: Hadoop HDFS > Issue Type: Bug > Components: name-node > Affects Versions: 0.20.1, 0.20.2, 0.21.0, 0.23.0 > Reporter: Uma Maheswara Rao G > Assignee: Uma Maheswara Rao G > Attachments: HDFS-1690.patch > > > Currently NameNode allows format command while it running. In this case the > command is executed partially (Lock file is deleted) and an exception thrown. > Because of this Name Node should be formatted after restart. This sort of > cases can happen accidentally. To prevent such cases Name Node should not > execute the format command partially while it is running. It can stright away > throw exception/log saying, Name Node is running. -- This message is automatically generated by JIRA.
