Matei Zaharia updated SPARK-1775:
---------------------------------
Priority: Critical (was: Major)
> Unneeded lock in ShuffleMapTask.deserializeInfo
> -----------------------------------------------
>
> Key: SPARK-1775
> URL: https://issues.apache.org/jira/browse/SPARK-1775
> Project: Spark
> Issue Type: Bug
> Components: Spark Core
> Affects Versions: 0.9.0, 1.0.0, 0.9.1
> Reporter: Matei Zaharia
> Assignee: Sandeep Singh
> Priority: Critical
> Labels: Starter
> Fix For: 1.0.0
>
>
> This was used in the past to have a cache of deserialized ShuffleMapTasks,
> but that's been removed, so there's no need for a lock. It slows down Spark
> when task descriptions are large, e.g. due to large lineage graphs or local
> variables.
