[ https://issues.apache.org/jira/browse/HUDI-484?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17005374#comment-17005374 ]
Pratyaksh Sharma commented on HUDI-484:
---------------------------------------
The above problem gets fixed by changing the line
String templateContent = FileIOUtils.readAsUTFString(this.getClass().getResourceAsStream("IncrementalPull.sqltemplate"));
to
String templateContent = FileIOUtils.readAsUTFString(this.getClass().getResourceAsStream("/IncrementalPull.sqltemplate"));

> 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}}
