Hi @huafengw, I haven't set the cluster up myself. It is one of our
corporate CDH 5.11.1 Hadoop cluster shared across multiple departments, secured
by Kerberos/Reverse Proxy/SSL. It is a 10 node cluster located in the company's
data center and protected by a corporate firewall (Security Layer 4) and
accessible only via application/edge servers with sufficient firewall rules to
access cluster services.
The above cluster was set up by our corporate CI department in cooperation
with Cloudera and it is mostly leaned on standard Cloudera 5 security
guidelines, nothing special in this respect.
The **YarnClient/Gear** commands are all executed from one of our edge
nodes, by an appropriate Kerberos principal.
