Aihua Xu commented on HIVE-10752:
---------------------------------

Sorry. That patch actually is not a revert. The patch will those NPE in at 
org.apache.hadoop.hive.serde2.ColumnProjectionUtils.toReadColumnIDString(ColumnProjectionUtils.java:190)
 since Ids is null.
Also for the cases that there are any projection prune, there will be still 
issues.

I posted the info in the parent jira as well.
