StandbyException should extend IOException
------------------------------------------
Key: HADOOP-7921
URL: https://issues.apache.org/jira/browse/HADOOP-7921
Project: Hadoop Common
Issue Type: Sub-task
Components: ha
Affects Versions: HA Branch (HDFS-1623)
Reporter: Todd Lipcon
Assignee: Todd Lipcon
In order to implement HDFS-2671 (HDFS methods should throw StandbyException
when in wrong state), we'd need to either add "throws StandbyException" to all
of the protocol APIs, or make StandbyException extend from IOException. The
latter is much simpler and less probability of it being a breaking change.
