--------------------------------
Summary: ERROR: Container complete event for unknown container id
Key: YARN-8695
URL: https://issues.apache.org/jira/browse/YARN-8695
Project: Hadoop YARN
Issue Type: Bug
Components: RM
Reporter: sivasankar
Have deployed a cluster with *3 data nodes*. YARN/MapReduce2/HDFS version is
*2.7.3* on HDP. While running teragen and Gobblin the following Yarn errors get
reported in the logs. Errors get reported only when the map tasks defined for
the job less than or equals to the number of data nodes in the cluster.
For *Teragen* -Dmapreduce.job.maps=4
For *Gobblin* mr.job.max.mappers=4
There are no errors if the map tasks(splits) are <= number of data nodes.
