> When we try to use HiveIncrementalPuller class to incrementally pull changes
> from hive, it throws NPE as it is unable to find IncrementalPull.sqltemplate
> in the bundled jar.
> Screenshot attached which shows the exception.
> The jar contains the template.
> Steps to reproduce -
> # copy hive-jdbc-2.3.1.jar, log4j-1.2.17.jar to docker/demo/config folder
> # run cd docker && ./setup_demo.sh
> # cat docker/demo/data/batch_1.json | kafkacat -b kafkabroker -t stock_ticks
> -P
> # {{docker exec -it adhoc-2 /bin/bash}}
> # {{spark-submit --class
