ajantha-bhat opened a new pull request #3577: [HOTFIX] Fix After alter table add column schemaOrdinal is not continuous URL: https://github.com/apache/carbondata/pull/3577 ### Why is this PR needed? Consider a scenario with complex columns[c1 int, c2 array<int>, c3 array<int>] here schema ordinal of child columns are -1. so c1, c2, c3 has ordinal 0, 1, 2. After alter table add column "c4 int", its ordinal should be 3. But currently it is 6 (due to flat column schema). This will give problem when this ordinal is referred for some other functionality like rearrange projection columns. ### What changes were proposed in this PR? make schema ordinal continuous by collecting previous schema ordinal max. ### Does this PR introduce any user interface change? - No ### Is any new testcase added? - No
