[jira] [Created] (HIVE-18116) Hive + HDFS EC Supportability and Testing Improvements

Sahil Takiar created HIVE-18116:
-----------------------------------

             Summary: Hive + HDFS EC Supportability and Testing Improvements
                 Key: HIVE-18116
                 URL: https://issues.apache.org/jira/browse/HIVE-18116
             Project: Hive
          Issue Type: Improvement
            Reporter: Sahil Takiar
            Assignee: Sahil Takiar


Now that we are on Hadoop 3.x, we can start integrating with HDFS Erasure Coding (see https://hadoop.apache.org/docs/r3.0.0-alpha2/hadoop-project-dist/hadoop-hdfs/HDFSErasureCoding.html for details).

First step is to add some tests using a custom CliDriver - we can do something similar to what we did for encryption.

Next step will be some supportability improvements - like printing out in the explain plan when a query is reading a EC file.
