[jira] [Created] (SPARK-3474) Rename the env variable SPARK_MASTER_IP to SPARK_MASTER_HOST

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

             Summary: Rename the env variable SPARK_MASTER_IP to SPARK_MASTER_HOST
                 Key: SPARK-3474
                 URL: https://issues.apache.org/jira/browse/SPARK-3474
             Project: Spark
          Issue Type: Bug
          Components: Deploy
    Affects Versions: 1.0.1
            Reporter: Chunjun Xiao


There's some inconsistency regarding the env variable used to specify the spark master host server.

In spark source code (MasterArguments.scala), the env variable is "SPARK_MASTER_HOST", while in the shell script (e.g., spark-env.sh, start-master.sh), it's named "SPARK_MASTER_IP".

This will introduce an issue in some case, e.g., if spark master is started  via "service spark-master start", which is built based on latest bigtop (refer to bigtop/spark-master.svc).
In this case, "SPARK_MASTER_IP" will have no effect.
I suggest we change SPARK_MASTER_IP in the shell script to SPARK_MASTER_HOST.
