Subject [jira] [Updated] (ACCUMULO-3528) Bump the version of HTrace to 3.1.0-incubating
Date Thu, 19 Feb 2015 19:01:12 GMT


Billie Rinaldi updated ACCUMULO-3528:
    Attachment: ACCUMULO-3528.1.patch

This patch updates the dependency, moves to using the new package name o.a.htrace, deletes
TraceRunnable/TraceCallable/TraceExecutorService in favor of using the htrace version of those
classes, and makes CompactionQueue use a Comparator so TraceRunnable does not need to be Comparable.

> 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
> See also HBASE-12810 for an example of upgrading htrace.  In addition to import changes,
it looks like span receivers and samplers are constructed differently now.
