Matei Zaharia updated SPARK-1775: --------------------------------- Fix Version/s: 0.9.2 > 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, 0.9.2 > > > 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. -- This message was sent by Atlassian JIRA (v6.2#6252)
