Josh Elser commented on ACCUMULO-3528:
--------------------------------------

bq. we may want to wait until Hadoop bumps their dependency too.

Do we know what version of Hadoop would contain this? 2.7.0?

It's tough because we're either broken "now" or "later" WRT HDFS spans. Will 
our code still run against the old htrace and the new incubating htrace runtime 
dependencies (e.g. can the user swap in the htrace impl they want to use on the 
classpath w/o having to recompile the code)?

> Bump the version of HTrace to 3.1.0-incubating

> Now that htrace has an incubating release, 3.1.0-incubating, we could use 
> that instead of 3.0.4.  This relates to HADOOP-11498.  The issue is that 
> tracing will only connect through to HDFS when Accumulo and HDFS are using 
> compatible versions of htrace, and the incubating release is not compatible 
> with previous versions since apache has been added to the package names.
