for example:

  test("dropping 1 aggregate table should not drop others") {
 sql(
   "create datamap preagg1 on table maintable using 'preaggregate' as 
select" +
   " a,sum(b) from maintable group by a")

   " a,sum(c) from maintable group by a")
 sql("drop datamap if exists preagg2 on table maintable")
 val showTables = sql("show tables")
 checkExistence(showTables, false, "maintable_preagg2")

showTables will always not contain maintable_preagg2, so we need adapt new 
show table function. There are some test case need check again.  @BJangir

this test case is invalid after you change the function of "show tables

[CARBONDATA-2094] Filter DataMap Tables in Show Table Command

Currently Show Table command shows datamap tables (agg tablels) but show 
table command should not show aggregate tables.

Solution :- Handle "show table "command in carbon side and Filter the 
datamap table and return rest of  the tables.
