Description

MV creation is not working with the sub string function. We are getting the spark.sql.AnalysisException while trying to create a MV with the substring and aggregate function. 

Spark -shell test queries:

 scala> carbon.sql("create datamap mv_substr using 'mv' as select sum(salary),substring(empname,2,5),designation from originTable group by substring(empname,2,5),designation").show(200,false)
org.apache.spark.sql.AnalysisException: Cannot create a table having a column whose name contains commas in Hive metastore. Table: `default`.`mv_substr_table`; Column: substring_empname,_2,_5;
