I am trying to write the Parquet files to Pubsub through Spark on a Dataproc cluster.
I have used below pseudo code
dataFrame
.as[MyCaseClass]
.foreachPartition(partition => {
val topicName = "projects/myproject/topics/mytopic"
val publisher = Publisher.newBuilder(topicName).build()
partition.foreach(users => {
try {
val jsonUser = users.asJson.noSpaces //using circe scala lib
val data = ByteString.copyFromUtf8(jsonUser)
val pubsubMessage = PubsubMessage.newBuilder().setData(data).build()
val message = publisher.publish(pubsubMessage)
}
catch {
case e: Exception => System.out.println("Exception in processing the event " + e.printStackTrace())
}
})
publisher.shutdown()
}
catch {
case e: Exception => System.out.println("Exception in processing the partition = " + e.printStackTrace())
}
}
)
Whenever I am submitting this on the cluster I am getting the spark prelaunch errors with exit code 134.
I have shaded the guava and protobuf in my pom. If I run this example through a local test case, it works but if submitted on dataproc I get the errors. I did not find any relative information about writing the data frame to pub-sub. Any pointers?
