Things to Come From the Cloudera/Hortonworks Merger

By Michael Arnold - February 16, 2019

Now that the two Hadoop distribution giants have merged, it is time to call out what will happen to their overlapping software offerings. The following are my predictions:

Ambari is out — replaced by Cloudera Manager.

This is a no-brainer for anyone that has used the two tools. People can rant and rave about open source and freedom all they want, but Cloudera Manager is light-years ahead of Ambari in terms of functionality and features. I mean, Ambari can only deploy a single cluster. CM can deploy multiple clusters. And the two features I personally use the most in my job as a consultant are nowhere to be found in Ambari: Host/Role layout and a non-default Configuration view.

Tez is out — replaced by Spark.

Cloudera has already declared that Spark has replaced MapReduce. There is little reason for Tez to remain as a Hive execution engine when Spark does the same things and can also be used for general computation outside of Hive.

Hive LLAP is out — replaced by Impala.

Similar to Tez, there is no reason to keep interactive query performance tools for Hive around when Impala was designed to do just that. Remember: Hive is for batch, and Impala is for exploration.
