Subject [jira] [Commented] (SPARK-4257) Spark master can only be accessed by hostname
Date Wed, 07 Jan 2015 08:07:34 GMT

    [ https://issues.apache.org/jira/browse/SPARK-4257?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14267387#comment-14267387

Alister Lee commented on SPARK-4257:
------------------------------------

Further, the spark URL is set correctly when SPARK_MASTER_IP is set, but not if the -h option
is used from sbin/start-master.sh.

eg. 
$ sbin/start-master.sh -h `hostname --ip-address`
starting org.apache.spark.deploy.master.Master, logging to /tmp/log/spark-ec2-user-org.apache.spark.deploy.master.Master-1-ip-172-31-12-155.out
$ grep spark:// /tmp/log/spark*.out
15/01/07 08:04:12 INFO Master: Starting Spark master at spark://ip-172-31-12-155:7077
$ sbin/stop-master.sh
stopping org.apache.spark.deploy.master.Master
$ export SPARK_MASTER_IP=`hostname --ip-address`
$ sbin/start-master.sh
starting org.apache.spark.deploy.master.Master, logging to /tmp/log/spark-ec2-user-org.apache.spark.deploy.master.Master-1-ip-172-31-12-155.out
$ grep spark:// /tmp/log/spark*.out
15/01/07 08:05:39 INFO Master: Starting Spark master at spark://172.31.12.155:7077

> After sbin/start-all.sh, the spark shell can not connect to standalone master by spark://IP:7077,
it works if replace IP by hostname.
> In the docs[1], it says use `spark://IP:PORT` to connect to master.
