[jira] [Updated] (SPARK-26672) SinglePartition may not satisfies
HashClusteredDistribution/OrderedDistribution
[ https://issues.apache.org/jira/browse/SPARK-26672?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Wang, Gang updated SPARK-26672:
-------------------------------
Summary: SinglePartition may not satisfies HashClusteredDistribution/OrderedDistribution (was: SinglePartition should not satisfies HashClusteredDistribution/OrderedDistribution)
> SinglePartition may not satisfies HashClusteredDistribution/OrderedDistribution
> -------------------------------------------------------------------------------
>
> Key: SPARK-26672
> URL: https://issues.apache.org/jira/browse/SPARK-26672
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 2.4.0
> Reporter: Wang, Gang
> Priority: Major
>
> If we are loading data to a *bucketed table* TEST_TABLE from another table SRC_TABLE(bucketed or not) with sql:
> insert overwrite table TEST_TABLE select * from SRC_TABLE limit 1000.
> Data inserted into TEST_TABLE will not be bucketed since after LimitExec the output partitioning will be SinglePartition, and in current logic, it satisfies the HashClusteredDistribution, so no shuffle will be added.
