>             Project: Apache Drill
>          Issue Type: Bug
>    Affects Versions: 1.13.0
>            Reporter: Bohdan Kazydub
>            Assignee: Bohdan Kazydub
>            Priority: Minor
>             Fix For: 1.14.0
> 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.
