* for each query, generate an unique id. * the id could describe some context information about the query, like start time, project name, etc. * for query thread, we could use query id as the name of the thread. As long as user logs thread's name, he can grep query log by query id afterwards. * pass query id to coprocessor, so that query id gets logged both in query server and region server. * BadQueryDetector should also log query id -- This message was sent by Atlassian JIRA (v6.3.4#6332)
