Subject [jira] [Commented] (ACCUMULO-4171) Update to htrace-core4
Date Tue, 29 Mar 2016 15:58:25 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-4171?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15216223#comment-15216223

Sean Busbey commented on ACCUMULO-4171:
---------------------------------------

When I've chatted with htrace and hadoop folks about the api stuff, especially changing versions
in Hadoop 2.y, the common refrain is that tracing in Hadoop has been experimental and so they're
not likely to settle until folks can see a solid story of what's going on inside Hadoop. FWIW,
htrace-3 was practically impossible to actually use in practice for HDFS from what I remember.

> We are currently using HTrace 3.1.0-incubating. There were some API changes and improvements
on the way to HTrace 4.x-incubating, and we should stay up to date with those changes.
