[SPARK-4120][SQL] Join of multiple tables with syntax like SELECT .. FROM
T1,T2,T3.. does not work in SparkSQL
Right now it works for only 2 tables like below query.
sql("SELECT * FROM records1 as a,records2 as b where a.key=b.key ")
But it does not work for more than 2 tables like below query
sql("SELECT * FROM records1 as a,records2 as b,records3 as c where
a.key=b.key and a.key=c.key").
