We're meeting same problem as karuppayya. when we trying to unpersist in
pyspark+zeppelin, memory dosen't released - so sc.stop for second hand,
zeppelin interpreter dies... I concern OOM error couldn't be escaped but is
there any possible way to use pyspark without this problem.
@karuppayya , how'bout uncache and make another sc or make sc to null
several times.. I think make sc newer in code is alter way to escape this
problem.
