Subject Re: Passing variables from %pyspark to %sh
Date Thu, 12 Jan 2017 14:56:48 GMT
Agree to share variables between interpreters. Currently zeppelin launch
one JVM for each interpreter group. So it is not possible to share
variables between spark and sh. But for some interpreters like sh, md, it
is not necessary to create separate JVM for them. We can embed them in
spark interpreter JVM.  But we could not do it for all interpreters,
because it would cause potential jar conflicts.
