> 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 org.apache.hudi.utilities.deltastreamer.HoodieDeltaStreamer $HUDI_UTILITIES_BUNDLE --storage-type COPY_ON_WRITE --source-class org.apache.hudi.utilities.sources.JsonKafkaSource --source-ordering-field ts --target-base-path /user/hive/warehouse/stock_ticks_cow --target-table stock_ticks_cow --props /var/demo/config/kafka-source.properties --schemaprovider-class org.apache.hudi.utilities.schema.FilebasedSchemaProvider}}
