HA: RetriableCommand is using RetryPolicy incorrectly after HADOOP-7896
-----------------------------------------------------------------------
Key: HADOOP-8116
URL: https://issues.apache.org/jira/browse/HADOOP-8116
Project: Hadoop Common
Issue Type: Sub-task
Components: util
Affects Versions: HA Branch (HDFS-1623)
Reporter: Aaron T. Myers
Assignee: Aaron T. Myers
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.
