[jira] [Commented] (SPARK-12306) Add an option to ignore BlockRDD partition data loss

If this > BlockManager were to lost because of some failure, then this BlockRDD would > throw a SparkException saying "Could not compute split, block not found". > In most cases this is the right thing to do. However, in a streaming scenario > where it can tolerant small pieces of data loss, maybe just move on silently > -- instead of throwing an exception -- is more preferable. > This issue proposes to add such an "spark.streaming.ignoreBlockNotFound" > option, which defaults to false, to tell whether to throw an exception or > just move on when a block is not found. -- 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

It doesn't sound like something that should be optionally ignored. I'd have to close this unless you can make a case for this, or at least describe it. > Add an option to ignore BlockRDD partition data loss > > > Key: SPARK-12306 > URL: https://issues.apache.org/jira/browse/SPARK-12306 > Project: Spark > Issue Type: Improvement > Components: Streaming >Affects Versions: 1.5.2 >Reporter: Liwei Lin > -- 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
