Jim Lohse commented on SPARK-11570:
-----------------------------------
Do you mean SPARK_LOCAL_IP? I don't see SPARK_LOCAL_HOSTNAME in spark-env.sh.
Thanks, if it exists and needs to be added to spark-env.sh I will submit a pull
request.
> ambiguous hostname resolving during startup
> -------------------------------------------
>
> Key: SPARK-11570
> URL: https://issues.apache.org/jira/browse/SPARK-11570
> Project: Spark
> Issue Type: Bug
> Components: Spark Core
> Affects Versions: 1.4.0, 1.4.1, 1.5.0, 1.5.1
> Environment: standalone
> Reporter: Sergey Soldatov
>
> when master is running in standalone mode, it expects that the hostname will
> be provided by --host. This is done by the start-master.sh script which sets
> --ip to `hostname` (doesn't it looks weird?).
> If someone running master directly (without start-master.sh), the hostname
> will be initialized as var host = Utils.localHostName(). Before SPARK-6440
> that was exactly the host name where master was started. But now it returns
> ip address instead. That would lead to worker connectivity problems (like you
> may observer in BIGTOP-2113). If ip addresses are prohibited, than var host
> should not be initialized in that way.
> Possible solutions - return the logic to set it to the host name or fail if
> no --host argument was provided.
