I am seeing this new exception while recovering from S3 on EC2 with 0.16.2.

I get a _lot_ of them.
I saw some mention of this error in regards to Lucene. Should I be
concerned?

Are you running several nodes on the same machine? Basically, thats the node trying to obtain a lock for its data location (/data/nodes/N), and it fails to obtain one.

Hmmm, not intentionally. Perhaps my web app did not shut down completely as
a new one is starting up. I am using Amazon's Elastic Beanstalk service, so
I suppose something may of been active in memory as a new web app was
deployed. I'll keep an eye on it in the future and see if any additional
Java processes are running.
I don't think that was the case since I would of expected port conflicts and
such as ES was starting up prior to receiving these exceptions.
