Matei Zaharia closed SPARK-542.
-------------------------------
Resolution: Won't Fix
New versions of Spark have ways to specify the hostname and IP address to bind
to that should address this issue.
> Cache Miss when machine have multiple hostname
> ----------------------------------------------
>
> Key: SPARK-542
> URL: https://issues.apache.org/jira/browse/SPARK-542
> Project: Spark
> Issue Type: Bug
> Components: Mesos
> Reporter: frankvictor
> Priority: Minor
>
> HI, I encountered a weird runtime of pagerank in last few day.
> After debugging the job, I found it was caused by the DNS name.
> The machines of my cluster have multiple hostname, for example, slave 1 have
> name (c001 and c001.cm.cluster)
> when spark adding cache in cacheTracker, it get "c001" and add cache use it.
> But when schedule task in SimpleJob, the msos offer give spark
> "c001.cm.cluster".
> so It will never get preferred location!
> I thinks spark should handle the multiple hostname case(by using ip instead
> of hostname, or some other methods).
> Thanks!
