'dfsadmin -safemode enter' should prevent the namenode from leaving safemode
automatically after startup
--------------------------------------------------------------------------------------------------------
Key: HADOOP-1980
URL: https://issues.apache.org/jira/browse/HADOOP-1980
Project: Hadoop
Issue Type: Bug
Components: dfs
Reporter: Koji Noguchi
Priority: Minor
When debugging, I'd like to be able to intentionally keep the FS in a safemode.
(For example, when looking at HADOOP-1978).
Also, it'll be nice if the namenode can still update the webUI/report when it
hits the dfs.safemode.threshold.pct.
