Sean Owen resolved SPARK-3563. ------------------------------ Resolution: Duplicate This is either 'not a problem' (leaking references to RDDs) or is another issue asking 'why does a shuffle file not get deleted?' which I'm hoping to direct to SPARK-5836. It's not quite a duplicate but I believe the underlying issue is the same. > Shuffle data not always be cleaned > ---------------------------------- > > Key: SPARK-3563 > URL: https://issues.apache.org/jira/browse/SPARK-3563 > Project: Spark > Issue Type: Bug > Components: Streaming > Affects Versions: 1.0.2 > Reporter: Hong Shen > > In our cluster, when we run a spark streaming job, after running for many > hours, the shuffle data seems not all be cleaned, here is the shuffle data: > -rw-r----- 1 tdwadmin users 23948 Sep 17 13:21 shuffle_132_34_0 > -rw-r----- 1 tdwadmin users 18237 Sep 17 13:32 shuffle_143_22_1 > -rw-r----- 1 tdwadmin users 22934 Sep 17 13:35 shuffle_146_15_0 > -rw-r----- 1 tdwadmin users 27666 Sep 17 13:35 shuffle_146_36_1 > -rw-r----- 1 tdwadmin users 12864 Sep 17 14:05 shuffle_176_12_0 > -rw-r----- 1 tdwadmin users 22115 Sep 17 14:05 shuffle_176_33_1 > -rw-r----- 1 tdwadmin users 15666 Sep 17 14:21 shuffle_192_0_1 > -rw-r----- 1 tdwadmin users 13916 Sep 17 14:38 shuffle_209_53_0 > -rw-r----- 1 tdwadmin users 20031 Sep 17 14:41 shuffle_212_26_0 > -rw-r----- 1 tdwadmin users 15158 Sep 17 14:41 shuffle_212_47_1 > -rw-r----- 1 tdwadmin users 42880 Sep 17 12:12 shuffle_63_1_1 > -rw-r----- 1 tdwadmin users 32030 Sep 17 12:14 shuffle_65_40_0 > -rw-r----- 1 tdwadmin users 34477 Sep 17 12:33 shuffle_84_2_1 > The shuffle data of stage 63, 65, 84, 132... are not cleaned. > In ContextCleaner, it maintains a weak reference for each RDD, > ShuffleDependency, and Broadcast of interest, to be processed when the > associated object goes out of scope of the application. Actual cleanup is > performed in a separate daemon thread. > There must be some reference for ShuffleDependency , and it's hard to find > out. -- 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
