Sean Owen commented on SPARK-17560:
-----------------------------------
It doesn't exist in Spark 1.4, and is an undocumented option. Behavior in 2.x
is not necessarily the same as 1.x, and as i understand SQL is generally case
insensitive now.
> SQLContext tables returns table names in lower case only

> Project: Spark
> Issue Type: Bug
> Affects Versions: 2.0.0
> Reporter: Aseem Bansal
>
> I registered a table using
> dataSet.createOrReplaceTempView("TestTable");
> Then I tried to get the list of tables using
> sparkSession.sqlContext().tableNames()
> but the name that I got was testtable. It used to give table names in proper
> case in Spark 1.4
