             Summary: Make metastore_db location of derby configurable in CarbonContext
                 Key: CARBONDATA-40
                 URL: https://issues.apache.org/jira/browse/CARBONDATA-40
             Project: CarbonData
          Issue Type: Improvement
            Reporter: Ravindra Pesala
            Assignee: Ravindra Pesala


Currently metastore_db location of derby is not configurable and it is always created in current directory. Because of this constraint user not able to create multiple CarbonContext with derby db. This is the reason user cannot create CarbonContext in spark-shell with standalone derby db.
To overcome the above issue we can make the derby db location configurable while creating CarbonContext.
Case 1:
{code}
val cc = new CarbonContext(sc)
{code}
In above scenario, default store location at `./carbondata` it means store is created in current directory.And default metastore location `./carbonmetastore`, it means metastore is created at current directory.

Case 2 :
{code}
val cc = new CarbonContext(sc, storeLocation)
{code}
In above scenario, default metastore location `./carbonmetastore`, it means metastore is created at current directory.

Case 3: 
{code}
val cc = new CarbonContext(sc, storeLocation, metastoreLocation)
{code}
In above scenario all parameters are passed, so store location and metastoreLocation would be created at desired location.
