Dongjoon Hyun commented on ORC-1251:
------------------------------------
Are you sure, [[email protected]]? It sounds like many Apache communities like
Apache Spark/Flink/ORC didn't support Apache Hadoop 2.7.3 so far as well. Could
you enlighten us a little more what is missing there?
> well, in that case, regardless of what the hadoop profile says, you only
> support hadoop 3.x
FYI, AFAIK, the following is Java 8 status summary and we've been using those
with old Hadoop 2 clusters.
- Since Apache Spark 2.2.0 (SPARK-19550), Apache Spark community has been
building and releasing with Java 8 only (2017)
- Since Apache Flink 1.4.0 (FLINK-7249), Apache Flink community has been
building and releasing with Java 8 only (2017)
- Since Apache ORC 1.6.0 (ORC-399), Apache ORC community has been building and
releasing with Java 8 only (2019)
Especially, Apache Spark has been using Apache Hadoop 2.7.3 profile since 2016
(SPARK-17558) until now.
