Subject Re: Is Apache Spark-2.2.1 compatible with Hadoop-3.0.0
Date Mon, 08 Jan 2018 18:17:14 GMT
My current best guess is that Spark does *not* fully support Hadoop 3.x
because https://issues.apache.org/jira/browse/SPARK-18673 (updates to Hive
shims for Hadoop 3.x) has not been resolved. There are also likely to be
transitive dependency conflicts which will need to be resolved.
