Apache Spark reassigned SPARK-17247: ------------------------------------ Assignee: Apache Spark > when fall back to hdfs is enabled for stats calculation, the hdfs listing and > size calcuation should be terminated as soon as total size > broadcast > threshold > -------------------------------------------------------------------------------------------------------------------------------------------------------------- > > Key: SPARK-17247 > URL: https://issues.apache.org/jira/browse/SPARK-17247 > Project: Spark > Issue Type: Bug > Reporter: Parth Brahmbhatt > Assignee: Apache Spark > > Currently when user enables spark.sql.statistics.fallBackToHdfs and no stats > are available from metastore we fall back to hdfs. This is useful join > optimization however this can slow things down. To speed up the operation we > could stop size calculation as soon as we hit the broadcast threshold as the > accuracy of size is not important. -- 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
