Todd Lipcon commented on HIVE-19685:
------------------------------------
Following is a screenshot of the trace view for the simple integration I've
been playing with:
!trace.png!
This makes it very easy to find issues like HIVE-19605 since the slow queries
stick out like a sore thumb. It's also helpful for clients of the HMS who have
also integrated opentracing -- it's easier to see how much of the total
operation time of a slow request can be attributed to the HMS vs other
contributing factors.

>
> When diagnosing performance of metastore operations it isn't always obvious
> why something took a long time. Using a tracing framework can provide an
> end-to-end view of an operation including time spent in dependent systems (eg
> filesystem operations, RDBMS queries, etc). This JIRA proposes to integrate
> OpenTracing, which is a vendor-neutral tracing API into the HMS server and
> client.
