Subject [jira] [Commented] (HDFS-2430) The number of failed or low-resource volumes the NN can tolerate should be configurable
Date Thu, 27 Oct 2011 23:26:33 GMT

    [ https://issues.apache.org/jira/browse/HDFS-2430?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13137734#comment-13137734
] 

Eli Collins commented on HDFS-2430:
-----------------------------------

Agree that option #1 is better. The notion of a NN "required" dir here parallels the notion
of a "critical" dir in the DN (proposed in HDFS-1848).  I'll check out the patch.

> 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.
