Sorry for the late reply @jeanlyn !
I think it's a bug of Hive DDL, which probably was resolved in Hive 0.14 /
0.15, and I am not sure if we really want to fix that in Spark SQL. @yhuai , do
you have any comment on this?
However, in this particular case, another work around in your product:
1) Rename the existed table;
2) Create a new table with schema you altered, and also the partitions.
3) Manually move the previous data into the new table folder from the HDFS.
4) Drop the old table.
