---------------------------------------
Summary: IPC client can raise UndeclaredThrowableException during
failure handling if maxwait==0
Key: HADOOP-13000
URL: https://issues.apache.org/jira/browse/HADOOP-13000
Project: Hadoop Common
Issue Type: Bug
Components: ipc
Affects Versions: 2.7.1
Reporter: Steve Loughran
When an IPC falls, it may goes into a retry process, which sleeps via
Thread.sleep() .
If this happens, and the max wait interval is set to 0, then an
InterruptedException can trigger in a Thread.sleep() operation. This isn't in
the method signatures, so gets wrapped in an UndeclaredThrowable. This isn't an
IOE, so all code catching IOEs get confused.
The original exception is also completely lost.
Proposed: InterruptedExceptions in the sleep are caught, trigger throwing of
the original exception instead
