Reynold Xin resolved SPARK-15365. --------------------------------- Resolution: Fixed Assignee: Parth Brahmbhatt Fix Version/s: 2.0.0 > Metastore relation should fallback to HDFS size if statistics are not > available from table meta data. > ----------------------------------------------------------------------------------------------------- > > Key: SPARK-15365 > URL: https://issues.apache.org/jira/browse/SPARK-15365 > Project: Spark > Issue Type: Improvement > Components: SQL > Reporter: Parth Brahmbhatt > Assignee: Parth Brahmbhatt > Fix For: 2.0.0 > > > Currently if a table is used in join operation we rely on Metastore returned > size to calculate if we can convert the operation to Broadcast join. This > optimization only kicks in for table's that have the statistics available in > metastore. Hive generally rolls over to HDFS if the statistics are not > available directly from metastore and this seems like a reasonable choice to > adopt given the optimization benefit of using broadcast joins. -- 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
