> 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.
