Re: [DISCUSSION]Merge index property and operations improvement.

Hi, 

Based on the final points considered, I have included the following 3 points
details of implementation and test cases in the document attached to JIRA.
https://issues.apache.org/jira/browse/CARBONDATA-4037
PR: https://github.com/apache/carbondata/pull/3988

1. make merge index by default enable and fail the compaction, load if the
merge index operation fails.
3. update table status file and the segment file only if the merge index
operation succeeds.
6. Alter compact command for merge index will not do anything for new
tables. It will merge for old tables only and do not delete the old index
files immediately

Inputs and suggestions for any changes are most welcomed.
