complete examples/batch/WordCount
Piotr Nowojski created FLINK-9969:
-------------------------------------
Summary: Unreasonable memory requirements to complete examples/batch/WordCount
Key: FLINK-9969
URL: https://issues.apache.org/jira/browse/FLINK-9969
Project: Flink
Issue Type: Bug
Components: ResourceManager
Affects Versions: 1.5.1, 1.5.0
Reporter: Piotr Nowojski
setup on AWS EMR:
* 5 worker nodes (m4.4xlarge nodes)
* 1 master node (m4.large)
following command fails with out of memory errors:
{noformat}
export HADOOP_CLASSPATH=`hadoop classpath`
./bin/flink run -m yarn-cluster -p 20 -yn 5 -ys 4 -ytm 16000 examples/batch/WordCount.jar{noformat}
Only increasing memory over 17.2GB example completes. At the same time after disabling flip6 following command succeeds:
{noformat}
export HADOOP_CLASSPATH=`hadoop classpath`
./bin/flink run -m yarn-cluster -p 20 -yn 5 -ys 4 -ytm 1000 examples/batch/WordCount.jar{noformat}
