Create a directory, for example, /usr/local/unravel-jars, for the JARs on the Unravel node in a cluster.

mkdir /usr/local/unravel-jars
chown -R unravel:unravel /usr/local/unravel-agent

Generate the JARs using the cluster-setup-scripts/unravel_hdp_setup.py script.

chmod +x <Installation directory>/install_bin/services/unravel/bin/install/cluster-setup-scripts/unravel_hdp_setup.py

cd <Installation directory>/install_bin/services/unravel/bin/install/cluster-setup-scripts/usr/local/unravel/install_bin/cluster-setup-scripts/

sudo python2 unravel_hdp_setup.py --sensor-only --unravel-server <unravel-host>:3000 --spark-version <spark-version> --hive-version <hive-version> --ambari-server <ambari-host> --btrace-dir /usr/local/unravel-jars/jars/btrace-agent.jar --hive-hook-dir /usr/local/unravel-jars/

Replace the values for unravel-host, spark-version, hive-version, and ambari-host with appropriate values.

For example:

python2 unravel_hdp_setup.py --sensor-only --unravel-server xyz66:3000 --spark-version 2.3.0 --hive-version 1.2.1 --btrace-dir /usr/local/unravel-jars/jars/btrace-agent.jar --hive-hook-dir /usr/local/unravel-jars/

Distribute /usr/local/unravel-jars to all worker, edge, and master nodes that run the queries.

For example,

scp -r /usr/local/unravel-jars root@hostname:/usr/local/

Make sure the node can reach port 4043 of Unravel Server.

If you are launching Spark actions:

Make sure that oozie.libpath for the Oozie shared library in HDFS is defined.

Copy the Hive Hook JAR and the Btrace JAR to oozie.libpath. If you don't do this, jobs controlled by Oozie 2.3+ fail.
