[jira] Updated: (HADOOP-3894) DFSClient chould log errors better, and provide better diagnostics

     [ https://issues.apache.org/jira/browse/HADOOP-3894?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Steve Loughran updated HADOOP-3894:
-----------------------------------

    Attachment: hadoop-3894.patch

This is an updated version of the patch.

# the parameter to processDatanodeError() has been removed. I had intended it to show the source file, but as that is in the this.src field, it is unneeded. The src field is used directly in the error message to tell you which file is unreachable

This code is a superset of HADOOP-4965; it adds the more detailed exception, and a test case that failed once the logging was added has been tweaked to catch the text and include a timeout on the submission.

> In my test runs I see a stack trace from DFSClient, because it isn't logging through the log APIs in its close() method. It should use the logger, for better error reporting
