Yann Byron commented on HUDI-2166:
----------------------------------
[~vbalaji] @Xu
If wanna support `drop columns` perfectly, need to wait
[RFC-33|[https://cwiki.apache.org/confluence/display/HUDI/RFC+-+33++Hudi+supports+more+comprehensive+Schema+Evolution].]
Otherwise, can not support the scene following correctly:
{code:java}
create table xx (uuid int, name string, ts long) using hudi
(preCombineField='ts')
as select 1, 'z3', 1000;
alter table xx drop columns (name);
alter table xx add columns (name string); {code}
> Support Alter table drop column
