HDFS-8722

Curious if anyone else has run into this one. Saw this one brought up 
over in an HBase JIRA issue. Seems to imply that write speed might be 
degraded by our WAL use in 2.7.1. Not sure if we should advertise any 
warning as I don't have a feeling yet for if we notice an ingest impact.

Cool. I'd be interested if you run any benchmarks. If I find some time, 
I'll throw up a few nodes and run some tests to see if I notice any sort 
of impact with continuous ingest.

Thanks, Eric.

I just started using 2.7.1, but I've not done any performance testing, yet.
