-----------------------------------
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.
