[jira] [Updated] (DRILL-6491) Prevent merge join for full outer
join at planning stage
[ https://issues.apache.org/jira/browse/DRILL-6491?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Bohdan Kazydub updated DRILL-6491:
----------------------------------
Description:
Currently, planner may choose merge join for full outer join for the case when another join types are enabled. When planner chooses merge join for full outer join an error is thrown when {{MergeJoinPOP}} is being created.
To fix this issue, the infinite cost should be set for merge rel node for the case when join type is full outer join.
