[CARBONDATA-326] Creates wrong table on 'create table like'
## Why raise this pr?
For fix this problem on jira:
```
I'm trying to create a table like my old table but it is not creating as
expected.
0: jdbc:hive2://localhost:10000> CREATE TABLE mainTable(id INT, name
STRING) STORED BY 'carbondata';
---------+
Result
---------+
---------+
No rows selected (0.206 seconds)
0: jdbc:hive2://localhost:10000> DESC mainTable;
-----------------------------+
col_name data_type comment
-----------------------------+
name string
id bigint
-----------------------------+
2 rows selected (0.056 seconds)
Above one is my mainTable and I wants to create copiedTable from it but
everytime it is show something like:
0: jdbc:hive2://localhost:10000> CREATE TABLE copiedTable LIKE mainTable;
---------+
result
---------+
---------+
No rows selected (0.101 seconds)
0: jdbc:hive2://localhost:10000> DESC copiedTable;
-------------------------------------------+
col_name data_type comment
-------------------------------------------+
col array<string> from deserializer
-------------------------------------------+
1 row selected (0.022 seconds)
0: jdbc:hive2://localhost:10000> LOAD DATA LOCAL INPATH
'hdfs://localhost:54310/user/hduser/datafiles/data.csv' INTO TABLE copiedTable
OPTIONS('DELIMITER'=',');
Error: java.lang.RuntimeException: Data loading failed. table not found:
knoldus.copiedtable (state=,code=0)
```
Since carbon not supprut 'create table like', when the table is carbon
table, we should throw error to the user and not create such a table,
meanwhile, we should also not have effect on hive tables.
## How to test?
Pass all the test cases and the new added testcase.
