Hi
I am trying to deploy an application in flink 1.12 having
hbase-shaded-client 2.1.0 as dependency in application mode
<https://ci.apache.org/projects/flink/flink-docs-stable/deployment/resource-providers/yarn.html#application-mode>.
On deploying the application I am seeing the below ClassCastException:
*org.apache.hadoop.yarn.proto.YarnServiceProtos$RegisterApplicationMasterRequestProto
cannot be cast to
org.apache.hadoop.hbase.shaded.com.google.protobuf.Message*
*I have done *export HADOOP_CLASSPATH=`hadoop classpath` as mentioned in
the hadoop documentation. I did not add any hadoop / hbase jars in the
flink/lib folder .
ubuntu@vrni-platform://tmp/debraj-flink/flink/lib$ ls
flink-csv-1.12.1.jar flink-json-1.12.1.jar
flink-table_2.12-1.12.1.jar log4j-1.2.17.jar
slf4j-log4j12-1.7.25.jar
flink-dist_2.12-1.12.1.jar flink-shaded-zookeeper-3.4.14.jar
flink-table-blink_2.12-1.12.1.jar log4j-to-slf4j-2.11.1.jar
vrni-flink-datadog-0.001-SNAPSHOT.jar
Can anyone suggest what could be going wrong here?
