 No

How has the community developed since the last report?

 There has been a bunch of mailing list activity relating directly to issue
 3 above e.g. better integration of HTrace into HBase/HDFS.  HTrace is
 being represented at ApacheCon 2015 NA in April with a presentation
 "Introducing Apache HTrace: An End-to-End Tracing Framework for
 Distributed Systems - Colin McCabe, Cloudera - http://sched.co/2P8Q

How has the project developed since the last report?

 The codebase has seen about 30 odd commits since last reporting.  Jira
 continues to see activity which is encouraging as HTrace community
 progresses towards next incubating release.

 1. Continue to grow the HTrace community

 3. Continue to explore the integration of the HTrace framework into other
    Apache products

Any issues that the Incubator PMC (IPMC) or ASF Board wish/need to be
aware of?

 Around January 20th HTrace successfully made the first release whilst in
 the Apache Incubator.  This was the outcomes of no-less than 10 release
 candidates and as many VOTE's.  In all every release candidate was very
 well managed with HTrace community providing excellent feedback to the
 release manager. Rather than then entire 10 release candidate exercise
 being a pain point for the community, it appears to have strengthened all
 involved. Well done HTrace.

How has the community developed since the last report?

 It is early incubating days for HTrace. The community has attracted in
 particular a new member who is doing a sterling job on a new UI for
 HTrace. Additionally it should be noted that the entire
 htrace-3.1.0-incubating release effort has certainly brought the existing
 community on leaps and bounds.

How has the project developed since the last report?

 The project has progressed significantly. In fact, it was highlighted on
 at least one occasion that documentation supporting a release candidate
 should be further clarified/improved due to the dynamic progressive nature
 of the HTrace codebase. As an early incubating project this is accepted as
 a positive move.

Shepherd/Mentor notes:

 John D. Ament (johndament):

   The podling is working through its first release slowly.  First release
   is always the hardest.  Good activity for a new podling on the lists,
   still waiting on the board report though.
