Subject [jira] Updated: (HADOOP-3678) Avoid spurious "DataXceiver: java.io.IOException: Connection reset by peer" errors in DataNode log
Date Tue, 01 Jul 2008 20:48:45 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-3678?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Raghu Angadi updated HADOOP-3678:
---------------------------------

    Description: When a client reads data using read(), it closes the sockets after it is
done. Often it might not read till the end of a block. The datanode on the other side keeps
writing data until the client connection is closed or end of the block is reached. If the
client does not read till the end of the block, Datanode writes an error message and stack
trace to the datanode log. It should not. This is not an error and it just pollutes the log
and confuses the user.  (was:
