Konstantin Boudnik commented on SPARK-11570: -------------------------------------------- Doing what the script does might be a way to go; or not. It is about hostname vs IP situation, because unless the hostname is specified _explicitly_ the master will use _an interface IP address_, which will render the whole cluster useless, because not a single worker will be able to associate with said master using its hostname. You see where I am going with this, right? The main problem here is that minor version updates are breaking integration interfaces with no good reason. > 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
