Aaron T. Myers updated HADOOP-8116:
-----------------------------------
Attachment: HADOOP-8116-HDFS-1623.patch
Here's a patch which addresses the issue. I also noticed while fixing this
issue that TestCopyMapper wouldn't have worked because HADOOP-8068 results in
an additional exception wrapping, which the test wasn't taking into account.
> HA: RetriableCommand is using RetryPolicy incorrectly after HADOOP-7896
> -----------------------------------------------------------------------

> Key: HADOOP-8116

> HADOOP-7896 (on the HA branch) refactored RetryAction from an enum to a
> class, and also moved the act of sleeping to delay retries from the
> RetryPolicy implementations into RetryInvocationHandler. RetriableCommand, in
> the rewritten distcp tool, uses RetryPolicy and associated classes from
> o.a.h.io.retry. When MAPREDUCE-2765 was merged into the HA branch,
> RetriableCommand wasn't adjusted accordingly to make use of the new structure
> of the o.a.h.io.retry classes.
> It's probably generally not kosher for RetriableCommand to be using the
> RetryPolicy classes at all, since they're not really intended to be used
> except by RetryInvocationHandler. But, regardless, this JIRA aims to make
> distcp's use of the o.a.h.io.retry classes functional again.
