Subject Accumulo SpanReceiver and related questions
Date Thu, 04 Jun 2015 19:04:34 GMT
Hi All,

I have only just started using Apache Htrace (so bear with me) in one of 
my projects and I would like to send all the traces that are created to 
an Apache Accumulo to store, similar to how the HBaseSpanReceiver 
currently does it. I have developed an initial version of an 
AccumuloSpanReceiver and as such, I have a few questions:

      1. How do I contribute my new AccumuloSpanReceiver back into the 
HTrace codebase? Is this by
          creating a Jira ticket and attaching a patch to it or would 
you rather a pull request in Github?

      2. I see that there is currently a couple of different GUI's for 
the display of traces, eg. one in
          htrace-hbase and another in htrace-htraced. Is there going to 
be some consolidation for the GUIs
          for the visualisation of traces with plugins for connecting to 
different data stores, eg. HBase,
          Accumulo, htraced, etc. or is it up to each sub-module to 
provide their own GUI implementation?

          In the interim, do you think that it would be a good approach 
for me to adapt the HBase GUI to
          also be able to display traces that are stored in Accumulo? If 
I was to do this, I think that pulling the
          webapp out of the htrace-hbase module into something like 
htrace-webapp would be better along with
          all the protobuf code into there also?

If I could get some advice before I get to far into this would be fantastic!
