> Curiously, ShellServerIT#trace() is failing for me on 1.7 and master, but
not 1.6.
Aha, 1.7 and master have the htrace dependency. I wonder if we worked
around something in cloudtrace.
> Tracing on client can sometimes lose "sendMutations" events.

> Project: Accumulo

> Reporter: Shawn Walker
> Assignee: Shawn Walker
> Priority: Minor
>
> In {{TabletServerBatchWriter.MutationWriter.queueMutations(...)}} (line 736),
> HTrace {{Span}}'s are not properly propagated across thread boundaries.
> Consequently, tracing doesn't propagate into
> {{TabletServerBatchWriter.SendTask.send(...)}}, and so the {{sendMutation}}
> event can fail to be logged.
> This can cause {{ShellServerIT.trace(...)}} to fail.
