> I found that Hive occasionally fails to print the user level explain due to

> {code:java}
> java.lang.Exception: Can not find the source operator on one of the branches
> of map join.
> at org.apache.hadoop.hive.common.jsonexplain.Op.inlineJoinOp(Op.java:173)

> This happens when a reducer vertex contains multiple join operators, and its
> top operator is DPHJ.
