In my jobmanager log I see this exception , probably is the root cause why the
whole job is killed…is there any memory problem in jobmanager ? any clue for
this error below?
I ran the yarn-session
And my flink-conf.yaml is pretty much unmodified
jobmanager.heap.mb: 256
taskmanager.heap.mb: 512
taskmanager.numberOfTaskSlots: 2
taskmanager.memory.preallocate: false
parallelism.default: 1
invoke of yarn-session.sh
HADOOP_CONF_DIR=/etc/hadoop/conf $FLINK_HOME/bin/yarn-session.sh -d -n 2 -s 1
-tm 2048
Thanks
The error in job manager is as below

Here is the line where NPE was thrown:
mainThread.interrupt(); // the main thread may be sleeping for the
discovery interval
I wonder if runFetcher() encountered running being false - otherwise mainThread
should not have been null.
Looks like we should check whether mainThread is null when shutting down.

Hi Ted, Sorry for my big font earlier…was not intended ☺
I am on flink 1.2.0
I built flink-connector-kinesis_2.10-1.2.0.jar from source and included in the
fatjar I am running.
Followed this
http://www.kidder.io/2017/02/15/flink-kinesis-streaming-connector/<https://na01.safelinks.protection.outlook.com/?url=http%3A%2F%2Fwww.kidder.io%2F2017%2F02%2F15%2Fflink-kinesis-streaming-connector%2F&data=01%7C01%7C%7Cfc97be832d1a4062d75608d482cf675f%7C0d009d13c2cd47d891dd2ae838b00d4b%7C0&sdata=avPl4%2FU5DTjZW09Zby9CeUttUNpiGWH%2Bvnycy9PhUDA%3D&reserved=0>
From code I read a kinesis stream using
consumerConfig.setProperty(ConsumerConfigConstants.AWS_REGION, region);
consumerConfig.setProperty(ConsumerConfigConstants.DEFAULT_STREAM_INITIAL_POSITION,
"LATEST");
consumerConfig.setProperty(ConsumerConfigConstants.AWS_CREDENTIALS_PROVIDER,
"AUTO");
consumerConfig.setProperty(ConsumerConfigConstants.SHARD_GETRECORDS_MAX, "10");
consumerConfig.setProperty(ConsumerConfigConstants.SHARD_GETRECORDS_RETRIES,
"200");
consumerConfig.setProperty(ConsumerConfigConstants.SHARD_GETRECORDS_INTERVAL_MILLIS,
"2000");
DataStream<Map<String, Object>> stream = env.addSource(new
FlinkKinesisConsumer<>(inputStream, new MyJsonDeserializationSchema(),
consumerConfig));
While I push the json event to the Kinesis stream intermittently I see this NPE
and flink job fails
