----------------------------------------------
Summary: Have webserver fall back to --hostname
Key: IMPALA-9102
URL: https://issues.apache.org/jira/browse/IMPALA-9102
Project: IMPALA
Issue Type: Improvement
Components: Infrastructure
Affects Versions: Impala 3.4.0
Reporter: Thomas Tauber-Marshall
Assignee: Thomas Tauber-Marshall
When the webserver determines its hostname, it first uses the value of
--webserver_interface. If this is a wildcard address, then it uses the value
returned by gethostname()
In some setups, gethostname() may return the short name and not the fqdn. This
is likely undesirable, eg. because it likely leads to the links to other
daemons on the /backends page not working.
In other places in Impala with the same basic issue, we allow users to set the
desired hostname with the --hostname flag. We should have the webserver fall
back to the value of --hostname, if set, before resorting to calling
gethostname()
