----------------------------------
Summary: Clean up Launcher and MapReduceLauncher after PIG-3419
Key: PIG-3524
URL: https://issues.apache.org/jira/browse/PIG-3524
Project: Pig
Issue Type: Bug
Components: impl
Affects Versions: 0.13.0
Reporter: Cheolsoo Park
Assignee: Cheolsoo Park
Fix For: 0.13.0
This is clean-up that I did for Launcher and MapReduceLauncher as part of
PIG-3502. I'd like to merge applicable changes from tez branch to trunk so that
they will not diverge too much over time.
The changes include:
# Rename ExecutionEngineKiller to HangingJobKiller and move it from PigContext
to Launcher. This brings back HangingJobKiller to its original place before
PIG-3419.
# Remove kill() method from the ExecutionEngine interface. It was needed only
by ExecutionEngineKiller, but after #1, it's no longer needed.
# Refactor Launcher and MapReduceLauncer classes. Basically, move MR-specific
stuff to MapReduceLauncher and common stuff to Launcher.
