Pengcheng Xiong commented on HIVE-13210:
----------------------------------------

[~jcamachorodriguez], shall we get this in ASAP as it blocks changes in HIVE-11160 of thrift
code? The changes in HIVE-12994 also affects serde and now if we run {code}mvn install -Pthriftif
-DskipTests -Dthrift.home=/usr/local{code} to regenerate thrift code, it will give us error

{code}
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.1:compile

> As we do not control what is written in the physical layer and thus we cannot ensure
NULLS ORDER (and even if we did, currently we do not take advantage of it), it seems exposing
the NULLS ORDER property at metastore level does not make much sense. We will revert that
part of patch HIVE-12994.
