How is Hadoop-3.0.0 's compatibility with olde

问题:

We are currently using hadoop-2.8.0 on a 10 node cluster and are planning to upgrade to latest hadoop-3.0.0.

I want to know whether there will be any issue if we use hadoop-3.0.0 with an older version of Spark and other components such as Hive, Pig and Sqoop.

回答1:

Latest Hive version does not support Hadoop3.0.It seems that Hive may be established on Spark or other calculating engines in the future.
