stack commented on HBASE-6524:
------------------------------
bq... so if you think the extra overhead from crating the TraceInfo is bad, I'm
happy to change it.
Its fine. Its a small object instantiation. Better if we didn't have to do it
but if it makes for cleaner hand off, its fine.
bq. ...or describe them more thoroughly in SpanReceiverHost.java? Or somewhere
else?
Its fine. The class comment in SpanReceiverHost is enough.
bq. ...maybe start a new span any time we talk to HDFS
Yeah, that sounds good. Can do that in new JIRA?
bq. I will work on a blog post.
I just think this a topic that will be of general interest.
For refguide, a sentence or two w/ pointers on how to set it all up would be
great.
I think we should commit this if its fine by you.
