How to Read hbase server side properties
Hi all,<br/>Is there any API to read server side properties which are set in hbase-site.xml..?? I did not get any information in the net.<br/><br/>Thanks and regards<br/>Vinay kashyap

HBaseConfiguration.create() loads the configuration from the hbase-site.xml
in the classpath.
If you have multiple hbase-site.xml you should put the one that you want to
use in the classpath.
The client hbase-site.xml doesn't need all the properties of the Master or
the Region Servers.
HBaseAdmin and all the other hbase classes are using
HBaseConfiguration.create() so there is no difference.
You must have the hbase-site.xml that you want to use in the classpath.
If you want to know the configuration that each server is running, you can
fetch it from the web-ui.

If you use this ctor of HBaseAdmin:
public HBaseAdmin(Configuration c)
throws MasterNotRunningException, ZooKeeperConnectionException {
this.conf = HBaseConfiguration.create(c);
HBaseAdmin would have an instance of HBaseConfiguration created as
described previously.
And getConfiguration() would just return this instance:
public Configuration getConfiguration() {
return this.conf;
}
Can you tell us what safety valve(s) your client tries to obtain ?

HbaseConfiguration.create() provides even the server side properties as wel..?? <br/>For eg., when using cloudera hadoop, I configure extra properties in region server safety valve and use in my hbase server. I want to obtain the value of one of the properties which is configured in the safety valve in my code.. Will I get those propeties from HBaseConfiguration.create(). I guess it is only to read and connect to the HBase server at client side..<br/><br/>I found another API, hBaseAdmin.getConfiguration(). The javadoc says it provides Configuration used by this instance. Do you guys think this API helps..?? I am yet to try this out..<br/><br/>Thanks and regards<br/>Vinay Kashyap

Minor correction: HBaseConfiguration.create()
This assumes access to hbase-site.xml is provided.

How about
BaseConfiguration.create() in package org.apache.hadoop.hbase?

Hi,
You can do a "curl <master/RS web ui>:<port>/conf" to get the current
configs that are being used by hbase daemons. You get the output in xml
format.
