Key: HADOOP-2213
URL: https://issues.apache.org/jira/browse/HADOOP-2213
Project: Hadoop
Issue Type: Bug
Components: dfs, mapred
Reporter: lohit vijayarenu
Priority: Minor
While namenode is in safemode, if a user submits a job they receive 'Job
tracker still initializing' exception. It would be good, if an appropriate
error message is thrown.
Job started: Thu Nov 15 23:15:39 UTC 2007
