Subject [jira] [Commented] (HDFS-2054) BlockSender.sendChunk() prints ERROR for connection closures encountered during transferToFully()
Date Thu, 09 Jun 2011 18:29:58 GMT

    [ https://issues.apache.org/jira/browse/HDFS-2054?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13046725#comment-13046725
] 

Patrick Kling commented on HDFS-2054:
-------------------------------------

If I remember correctly, the bug fixed by HDFS-1527 was causing the affected transfers to
fail silently. That's why I added this message. If it is polluting the log file, I have no
objection to downgrading this to a warning.

> The addition of ERROR was part of HDFS-1527. In environments where clients tear down
FSInputStream/connection before reaching the end of stream, this error message often pops
up. Since these are not really errors and especially not the fault of data node, the message
should be toned down at least. Assigning to the author of HDFS-1527.
