> PHOENIX-3752 is the JIRA to remove Hadoop Metrics-2 system from the Phoenix
> Framework, whose task is to deliver the received HTrace spans to the phoenix
> table. When replacing this system with a simple one as discussed on this
> JIRA, one of the current test {{testClientServerIndexingTracing()}} triggers
> a bug in Hadoop (HDFS-11583), which causes spurious {{writeTo}} spans being
> generated from {{DataStreamer}} class.
> Since Phoenix implements its {{SpanReceiver}} to receive the HTrace spans,
> all these spans are redirected over here, which eventually get persisted into
> Phoenix tables with the system developed in PHOENIX-3752. The information is
> useless and might use up unnecessary space.
> This JIRA is to add a patch to ignore those spans and prevent them from being
> written to Phoenix tables.
