Do I need to install Drill on each of the Hadoop data nodes or HBase RegionServer
Hi all,
For the distributed mode installation, I have some questions,
1) Do I need to install Drill to each Hadoop Data Node or HBase
RegionServer? Or I can install to any nodes in the cluster?
2) From the "Deploying Apache Drill in a Clustered Environment" in the
confluence page, mentions below:
"If you are using external JAR files, edit drill-env.sh, located in
/opt/drill/conf/, and define HADOOP_HOME:"
What is external JAR files? What is the purpose if I set the HADOOP_HOME?
Thanks!
George Lu

Drillbits can be installed on all nodes or any subset. Drill prefers to
have colocated nodes for better performance but this isn't a requirement
(e.g. Drillbit on same node as data node or regionserver).

That is very out of date. There is no longer any reason to set HADOOP_HOME.
The necessary hadoop jars are included in the drill installation.
