Subject [jira] Commented: (HADOOP-3574) Better Datanode DiskOutOfSpaceException handling.
Date Tue, 25 Nov 2008 21:48:46 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-3574?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12650754#action_12650754

Raghu Angadi commented on HADOOP-3574:

Informing others won't hurt . but HDFS should not depend on that for any important functionality
since this Datanode is already in bad state.. we can not expect it to do much.

> When a datanode ran out of disk space, it throws DiskOutOfSpaceException internally.
 However, it does not notify the writing client about the exception.  As a result, the client
will wait until socket timeout.
