[Spark 1.5.2]Check Foreign Key constraint

[Divya Gehlot]

Hi,
I am using Spark 1.5.2  with Apache Phoenix 4.4
As Spark 1.5.2 doesn't support subquery in where conditions .
https://issues.apache.org/jira/browse/SPARK-4226

Is there any alternative way to find foreign key constraints.
Would really appreciate the help.



Thanks,
Divya
