Szehon Ho commented on HIVE-9503: --------------------------------- Well its not overriding the meaning, the value means the same thing (size of small-tables), except for the clause that it depends on the first property. The name also makes sense as we don't use a conditional task in Spark. So I think having a Spark-only property for size of small-tables in mapjoin might be more confusing, as users will need to set both properties to get the same behavior in different execution engines. > 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)
