----------------------------
Status: Patch Available (was: Open)
> DFSInputStream#blockSeekTo may print incorrect warn msg for IOException
> -----------------------------------------------------------------------
>
> Key: HDFS-3927
> URL: https://issues.apache.org/jira/browse/HDFS-3927
> Project: Hadoop HDFS
> Issue Type: Bug
> Affects Versions: 3.0.0
> Reporter: Jing Zhao
> Assignee: Jing Zhao
> Priority: Minor
> Attachments: HDFS-3927.patch
>
>
> In DFSInputStream#blockSeekTo, for most IOExceptions (except
> InvalidEncryptionKeyException and InvalidBlockTokenException), the current
> code only prints "Failed to connect to targetAddr", which can be incorrect
> since there are other possible cases, e.g., the chosen node (remote/local)
> can be connected but the block/replica cannot be found. The correct error msg
> (including the error msg from remote node) should be printed to log.
