-------------------------------
Summary: Exception handling for InputInitializer
Key: TEZ-1703
URL: https://issues.apache.org/jira/browse/TEZ-1703
Project: Apache Tez
Issue Type: Bug
Reporter: Jeff Zhang
For handleInputInitializerEvent - this should be fairly straightfoward to
handle. At the moment this is an inline call from within the AsyncDispatcher,
and will end up causing a RuntimeException. The RuntimeException can be changed
to a AMUserCodeException which will take care of this.
For onVertexStateUpdated, this eventually gets invoked from within
RootInputInitializerManager. Catching exceptions there and sending a
RootInputInitialzierFailedEvent should be enough to fix this ? May require some
state machine changes to handle this event on a few more states.
