Nick Dimiduk commented on HBASE-14452:
--------------------------------------
Yeah, that's the idea. Ie, the site administrator can enable tracing on 1% of
all hbase client operations by editing hbase-site.xml. Root spans would not
have client application context, but it would enable operators to track the
behaviors of their infrastructure as experienced by their users.
> Allow enabling tracing from configuration

> Over on HDFS-8213 [~colinmccabe] convinced me that we should enable operators
> to trace HDFS requests independent of applications enabling the same. At the
> risk of adding a new, superset configuration, I think we should allow the
> same for HBase. Any objections to following HDFS's lead on this?
