URL: https://github.com/apache/carbondata/pull/4157
### Why is this PR needed?
- When the path is empty in Carbon add segments then
`StringIndexOutOfBoundsException `is thrown.
- Index server UT failures fix.
### What changes were proposed in this PR?
- Added check to see if the path is empty and then throw a valid error
message.
- Used `checkAnswer `instead of `assert `in test cases so that the order of
rows returned would be same with or without index server. Excluded 2 test cases
where explain with query statistics is used, as we are not setting any pruning
info from index server.
### Does this PR introduce any user interface change?
- No
### Is any new testcase added?
- Yes
