Jaeger tracing port?

Hello- I've been looking at Ceph's Jaeger tracing support, and was wondering why it uses port 6799 instead of the default 6831. It isn't compatible with the documentation directions for running Jaeger using vstart.sh, and it is also hard-coded in common/tracer.cc. Is there any reason why Ceph doesn't use the standard port, and/or why it couldn't be made configurable? Thanks! -Mike Neufeld
