[jira] Updated: (HADOOP-1980) 'dfsadmin -safemode enter' should prevent the namenode from leaving safemode automatically after startup

["Raghu Angadi (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/HADOOP-1980?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Raghu Angadi updated HADOOP-1980:
---------------------------------

    Attachment: HADOOP-1980.patch

Suggested patch for trunk.

If admin  puts NN in safemode during startup, NN will stay in safemode even after block ratios are satisfied. It also prints block ratios for convenience (just like the default case where admin does not enter safemode manually).

> 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.
