Is it tested whether this fix is backward compatible
(https://issues.apache.org/jira/browse/SPARK-23541) for 2.3.2? I see that fix
version is 2.4.0 in Jira. But quickly reviewing pull request
(https://github.com/apache/spark/pull/20698), it looks like all the code change
is limited to spark-sql
The message in question has already been public, and copied to mirrors the
ASF does not control, for a year and a half.
There is a process for requesting modification to ASF archives, but this
case does not qualify:
