Zheng Shao commented on HIVE-480:
---------------------------------
As a side note, the conf in hadoop is "mapred.max.tracker.failures" which
controls the number of maximum permitted failures for each task.
> allow option to retry map-reduce tasks

> Key: HIVE-480
> URL: https://issues.apache.org/jira/browse/HIVE-480
> Project: Hadoop Hive
> Issue Type: New Feature
> Components: Query Processor
> Reporter: Joydeep Sen Sarma
>
> for long running queries with multiple map-reduce jobs - this should help in
> dealing with any transient cluster failures without having to re-running all
> the tasks.
> ideally - the entire plan can be serialized out and the actual process of
> executing the workflow can be left to a pluggable workflow execution engine
> (since this is a problem that has been solved many times already).
