    [ https://issues.apache.org/jira/browse/SPARK-4257?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14201658#comment-14201658 ] 

jiezhou commented on SPARK-4257:
--------------------------------

In start-master.sh, the SPARK_MASTER_IP's default value is empty string, so it is set `hostname`.
And only if SPARK_MASTER_IP is explicitly set in advance in configuration file like   conf/spark-env.sh,  the spark shell can connect to standalone master by spark://IP: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.
