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

             Summary: Not able to pass custom environment variables in cluster to processes that spawning TaskManager
                 Key: FLINK-2954
                 URL: https://issues.apache.org/jira/browse/FLINK-2954
             Project: Flink
          Issue Type: Bug
          Components: Command-line client, Distributed Runtime
            Reporter: Jian Jiang
            Priority: Critical


There are programs that relies on custom environment variables. In hadoop mapreduce job we can use -Dmapreduce.map.env and - Dmapreduce.reduce.env to do pass them. Similarly in Spark
we can use --conf 'spark.executor.XXX=value for XXX'. There is no such feature yet in Flink.

This has given Flink a serious disadvantage when customers need such feature.
