Subject [GitHub] flink issue #2177: [FLINK-4127] Check API compatbility for 1.1 in flink-core

Github user rmetzger commented on the issue:

    https://github.com/apache/flink/pull/2177
  
    So you are suggesting to use the heap cutoff also for the JVM started in standalone mode?
    The cutoff was introduced for YARN because there is a difference in the amount of used
memory for a container we specify to YARN vs the memory the JVM is actually using.
    So if we specify a container of 1000 MB, it will be killed by YARN as soon as we use 1001
MBs. For operating systems, this doesn't apply and if users run into issues, the can just
set a lower heap size.
    For Mesos, I don't know how it behaves, but I hope that there is a similar requirement,
otherwise, we would have prematurely optimized the configuration keys.
    I'm against applying this mechanism to all JVMs we start.
    
    For the environment variables of the standalone mode, its quite easy to put the environment
variables into the config.sh file, or just set the env variables.
    But true, we could do a follow up JIRA to extract those env variables and set them in
the config.sh script.
