Apache Spark reassigned SPARK-14551: ------------------------------------ Assignee: (was: Apache Spark) > Reduce number of NN calls in OrcRelation with FileSourceStrategy mode > --------------------------------------------------------------------- > > Key: SPARK-14551 > URL: https://issues.apache.org/jira/browse/SPARK-14551 > Project: Spark > Issue Type: Improvement > Components: SQL > Reporter: Rajesh Balamohan > Priority: Minor > > When FileSourceStrategy is used, record reader is created which incurs a NN > call internally. Later in OrcRelation.unwrapOrcStructs, it ends ups reading > the file information to get the ObjectInspector. This incurs additional NN > call. It would be good to avoid this additional NN call (specifically for > partitioned datasets) -- 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
