hbase.master.port overridden programmatically?

Question

I installed hbase from cloudera 5.3.3 distribution and as I run the hbase everything seems to be working fine...

When I try assign hbase.master.port via /etc/hbase/conf/hbase-site.xml it does not pick it from there.

I see this from master node info http://MASTERNODE:60010/conf

<property>
  <name>hbase.master.port</name>
  <value>0</value>
  <source>programatically</source>
</property>

hbase distribution: 0.98.6-cdh5.3.3

What does this 'programmatically' mean and how can I disable/override it ?

What are you trying to achive here, are you trying to override Hbase master default port from 60010 ? – Phenolic

60010 is hbase.master.info.port ,and master.info.port is now changing everytime with every restart, this way hard to get good network approval – Peaked

Answer 1

answering my own question :(

as i just figured out the hbase standalone mode do not takes hbase.master.port into account
https://github.com/cloudera/hbase/blob/cdh4.5.0-release/src/main/java/org/apache/hadoop/hbase/LocalHBaseCluster.java#L141

standalone mode: http://www.cloudera.com/content/cloudera/en/documentation/core/v5-2-x/topics/cdh_ig_hbase_standalone_start.html

only way to assign a port is to setup ,at least a Pseudo-Distributed Mode, see this: http://www.cloudera.com/content/cloudera/en/documentation/core/v5-2-x/topics/cdh_ig_hbase_pseudo_configure.html

Answer 2

This means, its being set in some app/code.
Are you using Cloduera Manager?
You will need to set it in Cloduera Manager. If you are not using Cloudera Manager, then you will need to modify hbase-site.xml for HBase cluster and do a reboot of HBase cluster.

Hi Anil, I am not using cloudera manager, and I tried to use hbase-site.xml to configure it. Restarting hbase-master did not help. – Peaked

did you modify hbase-site.xml of node that is running hbase master? Is there any paritcular reason you dont want to use Cloudera Manager? It will make administration very easy. – Hillari

ok. in that case, can you post this on cloudera forums. This is more of a question to cloudera(groups.google.com/a/cloudera.org/forum/#!forum/cdh-user) at this point. – Hillari

Answer 3

Since version 1.4.2 there's hbase.localcluster.assign.random.ports option which prevents ports overriding
