Xuefu Zhang commented on HIVE-9503: ----------------------------------- I'm not sure of the difference between backup task and the "conditional task" that these two properties are referring to, but I don't feel we need a property to control whether to have a backup task. As long as we auto converted a join, we should have a backup task. > Update 'hive.auto.convert.join.noconditionaltask.*' descriptions > ---------------------------------------------------------------- > > Key: HIVE-9503 > URL: https://issues.apache.org/jira/browse/HIVE-9503 > Project: Hive > Issue Type: Bug > Components: Configuration > Reporter: Szehon Ho > Priority: Minor > > 'hive.auto.convert.join.noconditionaltask' flag does not apply to Spark or > Tez, and only to MR (which has the legacy conditional mapjoin) > However, 'hive.auto.convert.join.noconditionaltask.size' flag does apply to > Spark, Tez, and MR, even though the description indicates it only applies if > the above flag is on, which is true only for MR. > These configs should be updated to reflect this case. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
