REST API: empty reply from server, for "remove_previous_stacks"

[Eirik Thorsnes <ei...@norceresearch.no>]

Hi,

I've previously used the "remove_previous_stacks" command on the REST
API for deleting old rpms in the cluster.

I'm tried this again now with ambari version 2.6.2.0-155 (Hortonworks
compile, Centos 7 OS, Oracle 1.8u181 jdk) and I get no reply on the API,
and no job is scheduled in the UI. There is also no messages related to
this, even in DEBUG mode, in the ambari server log.

Note that GET request to the API for e.g. host_components works and
gives correct output.

Here is the output from the failed command:

date && curl --insecure -v

Is this API command removed in this version?
