Saisai Shao updated LIVY-411:
-----------------------------
Description:
In Livy 0.5.0, we supported multiple languages in one session, but it requires
that the packages should be available, such as R package and Python package,
otherwise session will be failed to create. However, in some cases python or R
package may be missing in Spark distro, this will make Livy fail to creation
interactive session.
To fix this issue, we should not force such restriction on session creation,
but delay the check until related interpreter is used. If such packaging is
missing, we should make the related execution failure and return user the cause
of issue, but don't affect other correctly started interpreters.
