[WIP] Fixed query failure in fileformat due stale cache issue
**Problem**
While using FileFormat API, if a table created, dropped and then recreated
with the same name the query fails because of schema mismatch issue
**Analysis**
In case of carbondata used through FileFormat API, once a table is dropped
and recreated with the same name again then because the dataMap contains the
stale carbon table schema mismatch exception is thrown
**Solution**
To avoid such scenarios it is always better to update the carbon table
object retrieved
