Subject [jira] [Commented] (ACCUMULO-3715) Decrease sampling percentage for tracing
Date Wed, 08 Apr 2015 22:23:12 GMT

Billie Rinaldi commented on ACCUMULO-3715:
------------------------------------------

I've posted a patch on review board.  It possible we could just start dropping 0ms spans and
not need the additional sampling configuration, so we should decide if we want to keep that
or not.

> Now that HDFS has tracing, individual traces might collect much more tracing data than
they did previously.  We should have a way of controlling how much tracing data is collected
other than just turning off HDFS tracing.
