Subject [jira] [Commented] (HDFS-2430) The number of failed or low-resource volumes the NN can tolerate should be configurable
Date Tue, 11 Oct 2011 18:07:11 GMT

    [ https://issues.apache.org/jira/browse/HDFS-2430?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13125238#comment-13125238
] 

Suresh Srinivas commented on HDFS-2430:
---------------------------------------

Aaron, with the patch from HDFS-2422, the javadoc for NameNodeResourceChecker is not valid.
It says {{<code>hasAvailableDiskSpace</code> - which will return true if and only
if the NameNode has disk space available on all volumes which are configured to be checked}}.
Can you please address that in HDFS-2430.

> Currently the number of failed or low-resource volumes the NN can tolerate is effectively
hard-coded at 1. It would be nice if this were configurable.
