Failed job not throwing exception

[Nick Buroojy <ni...@civitaslearning.com>]

Hi All,

I'm seeing some odd behavior with a Spark-Elasticsearch loading job. The
load seems to fail, it only loads part of the data, and there is a
stacktrace on the Driver, but there is no exception propagated to the top
level. Has anyone seen "swallowed" failures before?

We're using spark 1.5.2
