-------------------------------

             Summary: YARN: JM and TM Memory must be specified with Units 
                 Key: FLINK-9777
                 URL: https://issues.apache.org/jira/browse/FLINK-9777
             Project: Flink
          Issue Type: Bug
          Components: Documentation, YARN
    Affects Versions: 1.6.0
            Reporter: Gary Yao
             Fix For: 1.6.0


With FLINK-6469, the JobManager and TaskManager memory must be specified with units (otherwise bytes are assumed). The command to start a YARN session as documented ([https://github.com/apache/flink/blob/9f736d1927c62d220a82931c4f5ffa4955910f27/docs/ops/deployment/yarn_setup.md) |https://github.com/apache/flink/blob/9f736d1927c62d220a82931c4f5ffa4955910f27/docs/ops/deployment/yarn_setup.md] would not work because 1024 bytes and 4096 bytes are not enough for the heap size. The command finishes with the following exception:
