Re: [DISCUSS] Htrace4, Hadoop 2.7

2016-07-07 Thread Christopher
I'm sure I know some people trying to use Accumulo+HDFS tracing, and it's going to cause a problem no matter what, because Hadoop and Accumulo aren't always upgraded at the same time. I just want to make sure it gets better at some point, if both are sufficiently up-to-date. Backporting patches to

Ah, that makes more sense. I would be fine with bumping the htrace dependency to match the most recent version of Hadoop that we support and not doing a shim layer. We might want to check in with any users who are using the Accumulo+HDFS tracing to see if this would be a problem for them. I am not

Ah, my mistake. I thought it was 2.7 and later. Well, then I guess the question is whether we should bump to 2.8, then. I'm not a fan of the shim layer. I'd rather provide support for downstream packagers trying to backport for HTrace3, if anybody ends up requiring that, than provide a shim to pres

I'm in favor of bumping our Hadoop version to 2.7. We are already on the same htrace version as Hadoop 2.7. (The discussion in ACCUMULO-4171 is relevant to Hadoop 2.8 and later.) Billie On Thu, Jul 7, 2016 at 2:20 PM, Christopher wrote: > Thinking about https://issues.apache.org/jira/browse/ACC

[DISCUSS] Htrace4, Hadoop 2.7

2016-07-07 Thread Christopher
Thinking about https://issues.apache.org/jira/browse/ACCUMULO-4171, I'm of the opinion that we should probably bump our Hadoop version to 2.7 and HTrace version to what Hadoop is using, to keep them in sync. Does anybody disagree?
