> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: hdfs client
> Affects Versions: 0.20.203.1
> Reporter: Suresh Srinivas
> Assignee: Suresh Srinivas
> Priority: Minor
> Fix For: 0.23.0

>
> When client fails to connect to one of the datanodes from the list of block
> locations returned, exception stack trace is printed in the client log. This
> is an expected failure scenario that is handled at the client, by going to
> the next location. Printing entire stack trace is unnecessary and just
> printing the exception message should be sufficient.
