Subject [jira] Updated: (HADOOP-1980) 'dfsadmin -safemode enter' should prevent the namenode from leaving safemode automatically after startup
Date Wed, 19 Nov 2008 00:19:44 GMT

     [ 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.
