Herman van Hovell commented on SPARK-14199:
-------------------------------------------
Correlated sub-queries are currently not supported.
It also appears that you are using some Spark extension:
{{org.apache.spark.sql.hive.huawei.rules.analyze.UnrelatedSubqueryConversion}}.
We really cannot help you with that. I am closing this.
