Spark BlockManager: use IP?

Thu, 26 Feb 2015 14:03:57 -0800 

Hi All,

Using DSE 4.6.1 (Spark 1.1.0.2).

I am having trouble convincing BlockManager in a Spark Worker process to use a 
machine’s IP instead of its hostname. Everything else in the Spark Workers is 
using the IP correctly.

ERROR 2015-02-26 21:49:01 org.apache.spark.network.SendingConnection: Error 
connecting to 3a831deac5a5:42000

Any suggestions, tricks, recommendations?

Thanks!
