Eric Liang created SPARK-17701: ---------------------------------- Summary: Refactor DataSourceScanExec so its sameResult call does not compare strings Key: SPARK-17701 URL: https://issues.apache.org/jira/browse/SPARK-17701 Project: Spark Issue Type: Improvement Reporter: Eric Liang
Currently, RowDataSourceScanExec and FileSourceScanExec rely on a "metadata" string map to implement equality comparison, since the RDDs they depend on cannot be directly compared. This has resulted in a number of correctness bugs around exchange reuse, e.g. SPARK-17673 and SPARK-16818. To make these comparisons less brittle, we should refactor these classes to compare constructor parameters directly instead of relying on the metadata map. -- 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
