Peeyush Bishnoi commented on FALCON-1618:
-----------------------------------------
[~saktheesh] I have replicated the provided Falcon entity and it works in my
environment which is on HDP2.3 version itself. From the oozie-site.xml can you
ensure that dataIn EL extension is defined.
{code:java}
$ cat /etc/oozie/conf/oozie-site.xml | grep dataIn
dataIn=org.apache.oozie.extensions.OozieELExtensions#ph3_dataIn,
dataIn=org.apache.oozie.extensions.OozieELExtensions#ph1_dataIn_echo,
{code}
Also ensure that following jar file must be available:
/usr/hdp/current/oozie-server/libext/falcon-oozie-el-extension-*.jar
> Unable to run OOZIE (MapReduce) workflow through Falcon Process
