Date Wed, 20 Apr 2016 16:04:25 GMT
Chunhui Shi created DRILL-4620:

             Summary: Drill query Hbase table got base64 encoded results while Hbase Shell
show table content correctly 
                 Key: DRILL-4620
                 URL: https://issues.apache.org/jira/browse/DRILL-4620
             Project: Apache Drill
          Issue Type: Bug
            Reporter: Chunhui Shi

Create a table using hbase shell following the steps in https://www.mapr.com/blog/secondary-indexing-mapr-db-using-elasticsearch.
However query the generated table in drill showing base64 encoded results but not the correct
plaintext. As shown below:

[root@atsqa4-128 ~]# hbase shell
HBase Shell; enter 'help<RETURN>' for list of supported commands.
Type "exit<RETURN>" to leave the HBase Shell
Version 0.98.12-mapr-1602, rcf7a299d9b0a24150d4a13cbce7fc9eac9b2404d, Tue Mar  1 19:32:45
UTC 2016

Not all HBase shell commands are applicable to MapR tables.
Consult MapR documentation for the list of supported commands.
