You would usually go to the livy installation directory and check the livy.jar version.
I am on an EMR and the path for jars is /usr/lib/livy/jars/. So I tried :
[root@host jars]# ls /usr/lib/livy/jars/ | grep livy
livy-api-0.7.0-incubating.jar
livy-client-common-0.7.0-incubating.jar
livy-core_2.11-0.7.0-incubating.jar
livy-rsc-0.7.0-incubating.jar
livy-server-0.7.0-incubating.jar
on a node with livy installed:
run
ls -l /usr/hdp/current/livy2-server/jars/livy-{server,client}*output:
this is version 0.4.0 apparently (on a cluster running HDP 2.6.3.0).
not the most elegant way - but seems to work.
