Description
Be more defensive about calling
Option.get
onmaterializedSourceRDD
and check first that it's actuallySome
. In fact only invoke the entire branch where we log only when we actually did materialize the source (and not, say, ran out of disk space before).How was this patch tested?
This PR adds a new test for the scenario where we throw an out of disk space error without having materialized the source.
Does this PR introduce any user-facing changes?
No
