Apache Spark reassigned SPARK-23827: ------------------------------------ Assignee: Apache Spark (was: Tathagata Das) > StreamingJoinExec should ensure that input data is partitioned into specific > number of partitions > ------------------------------------------------------------------------------------------------- > > Key: SPARK-23827 > URL: https://issues.apache.org/jira/browse/SPARK-23827 > Project: Spark > Issue Type: Bug > Components: Structured Streaming > Affects Versions: 2.3.0 > Reporter: Tathagata Das > Assignee: Apache Spark > Priority: Critical > > Currently, the requiredChildDistribution does not specify the partitions. > This can cause the weird corner cases where the child's distribution is > `SinglePartition` which satisfies the required distribution of > `ClusterDistribution(no-num-partition-requirement)`, thus eliminating the > shuffle needed to repartition input data into the required number of > partitions (i.e. same as state stores). That can lead to "file not found" > errors on the state store delta files as the micro-batch-with-no-shuffle will > not run certain tasks and therefore not generate the expected state store > delta files. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
