I deployed the latest version of Apache Impala from:
http://www.apache.org/dyn/closer.cgi?action=download&filename=impala/3.3.0/apache-impala-3.3.0.tar.gz
and to see its used ports I used netstat -- listen (see below). Instead of 21000 I tried to use 31000 as the used ports by Impala are described at:
https://www.cloudera.com/documentation/enterprise/5-14-x/topics/impala_ports.html
but could not connect from an impala-shell located at another computer (Tried 21000 but failed, too). Am I missing something? The impala daemon is running as if I do
root@bb9f4792e21d:/opt/Impala/bin# ps -ef | grep -i impalad
root 23067 1 0 15:31 pts/0 00:00:00 grep --color=auto -i impalad
I can see it is running.
root@bb9f4792e21d:/opt/Impala/bin# netstat --listen
