Description

I'm trying to collect CPU profiles using pprof from gperftools. I'm launching a CPU profile from a client machine outside the cluster as follows:

pprof --text /path/to/impalad http://<hostname>:25000/pprof/profile

The impalad on <hostname> does generate the raw profile data and write it to a file in <hostname>:/tmp, but nothing is returned to the client machine.
