Hi, all the sub tasks for HBASE-22120 has been resolved. And in https://issues.apache.org/jira/browse/HBASE-23762, I added a simple documentation on how to enable tracing in HBase.
PTAL at the big PR https://github.com/apache/hbase/pull/2901 If no big concerns, I will start a vote later to merge the branch back to master.
