Andrew Or resolved SPARK-15736. ------------------------------- Resolution: Fixed Fix Version/s: 2.0.0 1.6.2 > Gracefully handle loss of DiskStore files > ----------------------------------------- > > Key: SPARK-15736 > URL: https://issues.apache.org/jira/browse/SPARK-15736 > Project: Spark > Issue Type: Bug > Components: Block Manager > Affects Versions: 1.6.0 > Reporter: Josh Rosen > Assignee: Josh Rosen > Fix For: 1.6.2, 2.0.0 > > > If an RDD partition is cached on disk and the DiskStore file is lost, then > reads of that cached partition will fail and the missing partition is > supposed to be recomputed by a new task attempt. In the current BlockManager > implementation, however, the missing file does not trigger any metadata > updates / does not invalidate the cache, so subsequent task attempts will be > scheduled on the same executor and the doomed read will be repeatedly > retried, leading to repeated task failures and eventually a total job failure. > In order to fix this problem, the executor with the missing file needs to > properly mark the corresponding block as missing so that it stops advertising > itself as a cache location for that block. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
