[CARBONDATA-3801][CARBONDATA-3805][CARBONDATA-3809] Query on partition table with SI having multiple partition columns gives empty results Why is this PR needed? 1. Query on partition table with SI having multiple partition columns gives empty results. Because while loading data to SI table, blockid -> partition directory path is replaced by '#' instead of '/' to support multi level partitioning. Hence block id will be like part1=1#part2=2/xxxxxxxxx. During query the above block id is compared with actual block id part1=1/part2=2/xxxxxxxxx, which do not match, and provides empty results. 2. Drop Index throws exception while starting beeline, that error while editing schema file 3. Refresh syntax in SI doc is wrong. What changes were proposed in this PR? 1. During query, convert block id as in Load flow in case of partition table, to support multi level partitioning. 2. Remove modifying schema mdt file in index flow. 3. Updated Refresh syntax This closes #3748
