Yup, that would be the perfect place to start. And yes, I'll assign this jira to you. Thanks
for working on it! :)

> Currently, we do not support mixing dynamic partitioning and append in the same job.
One reason is that we need exhaustive testing of corner cases for that, and a second reason
is the behaviour of add_partitions. To support dynamic partitioning with append, we'd have
to have a add_partitions_if_not_exist call, rather than an add_partitions call.
> Thus, the current implementation in HIVE-6475 assumes immutability for all dynamic partitioning
jobs, irrespective of whether or not the table is marked as mutable or not.
