ajantha-bhat opened a new pull request #3729:
URL: https://github.com/apache/carbondata/pull/3729
### Why is this PR needed?
Consider a scentio of upgrade from 1.6 carbon jars to 2.0,
carbo.storelocation is s3a, but spark.sql.warehouse.dir is not configured.
Once upgrade is done and refresh is performed. Latest 2.0 takes path from
spark.sql.warehouse.dir, so hive table will have default fs warehouse location.
Which is wrong location.
So, need to allow user to configure spark.sql.warehouse.dir properly and do
refresh again.
But ew are not allowing refresh again as table already present in hive,
### What changes were proposed in this PR?
Allow refresh again even if table exists in hive
### Does this PR introduce any user interface change?
- No
### Is any new testcase added?
- No
