Cheng Lian commented on SPARK-9783: ----------------------------------- cc [~yhuai] > Use SqlNewHadoopRDD in JSONRelation to eliminate extra refresh() call > --------------------------------------------------------------------- > > Key: SPARK-9783 > URL: https://issues.apache.org/jira/browse/SPARK-9783 > Project: Spark > Issue Type: Bug > Components: SQL > Affects Versions: 1.5.0 > Reporter: Cheng Lian > Assignee: Cheng Lian > Priority: Blocker > > PR #8035 made a quick fix for SPARK-9743 by introducing an extra > {{refresh()}} call in {{JSONRelation.buildScan}}. Obviously it hurts > performance. To overcome this, we can use {{SqlNewHadoopRDD}} there and > override {{listStatus()}} to inject cached {{FileStatus}} instances, similar > as what we did in {{ParquetRelation}}. -- 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
