Apache Drill is an open source, low-latency query engine for Hadoop that delivers secure, interactive SQL analytics at petabyte scale. With the ability to discover schemas on-the-fly, Drill is a pioneer in delivering self-service data exploration capabilities on data stored in multiple formats in files or NoSQL databases. By adhering to ANSI SQL standards, Drill does not require a learning curve and integrates seamlessly with visualization tools. Source

Tutorial:

Grab latest version of drill

wget http://getdrill.org/drill/download/apache-drill-1.2.0.tar.gz tar xvfz apache-drill-1.2.0.tar.gz /root/drill/apache-drill-1.2.0

[root@node1 apache-drill-1.2.0]# cd bin/

Start Drill in distributed mode ( You can start in embedded mode too)

[root@node1 conf]# ../bin/drillbit.shstart

starting drillbit, logging to /root/drill/apache-drill-1.2.0/log/drillbit.out

Drill Web Console - http://host:8047

Enable storage plugins

Click Storage --> Enable hbase,hive,mongo

Modify storage plugin for Hive and HBase as per your Hadoop cluster setup

for example: click update for hive under storage plugins

modify hive.metastore.uris

Hive Test: launch hive shell

hive> create table drill_hive ( info string);

hive> insert into table drill_hive values ('This is Hive and you are using Drill');

[root@node1 bin]# ./drill-conf

apache drill 1.2.0

"start your sql engine"

0: jdbc:drill:> use hive;

0: jdbc:drill:> select info from drill_hive;

HBase

Change storegae properties in case HBase zookeeper.znode.parent points to /hbase-unsecure

add "zookeeper.znode.parent": "/hbase-unsecure"

Let's check the query plan and metrics

Click Profile

You will see queries under completed queries.

Hi Neeraj - Thanks for the post. Since current HDP doesn't ship with Drill , would it be reasonable to expect using the Drill ODBC Driver for HBASE Connectivity from Excel and other BI tools ? ( though its more of a MAPR Focus?) I would rather maintain one ODBC Driver vs having Drill for HBASE and HDP ODBC for Hive.

@Davide Vergari just released a custom Ambari service to install Apache Drill thru Ambari on HDP 2.4. Feel free to take a look at it.
