Subject [jira] [Resolved] (AMBARI-12972) Ambari uses port 8080 as default port for hbase.rest.port for knox topology
Date Fri, 12 Jan 2018 22:35:00 GMT

     [ https://issues.apache.org/jira/browse/AMBARI-12972?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Jaimin Jetly resolved AMBARI-12972.
-----------------------------------
    Resolution: Fixed

[~pradeep_bhadani]
if hbase.rest.port is not defined in the hbase-site then hbase rest server will start at 8080
port ([hbase-defaults.xml|https://github.com/apache/hbase/blob/master/hbase-common/src/main/resources/hbase-default.xml#L1162])

That's why Knox config needs to point to default hbase.rest.port value it is not defined.
Making sure that Hbase rest server does not have conflicting port with any other service (including
ambari) is admin's responsibility as HBase Rest server is not being managed as a component
by Ambari as of now. Admin can solve any port conflict issue over here by adding config hbase.rest.port
to hbase-site via ambari-web with different value than 8080

I am closing this issue from above explanation. Please reopen this issue if you think otherwise.

> By default , Ambari use the port 8080 for hbase.rest.port in knox topology XML file.
But port 8080 is used by ambari itself (if ambari server and knox are on same machine) which
leads to conflicts and user cannot access hbase REST via knox.
