Daryn Sharp commented on HDFS-5881:
-----------------------------------
Thinking about it further, this really should a hard exception. In this
particular case, the client happens to recover on "accident" from the bad seek
logic when it falls over to another DN. However I could envision future
scenarios where a logic error causes it to seek to the wrong location and _not_
fail.
> Fix skip() of the short-circuit local reader (legacy).

> It looks like a bug in skip() was introduced by HDFS-2356 and got fixed as a
> part of HDFS-2834, which is an API change JIRA. This bug causes to skip more

> It is only for branch-0.23.
