How to validate HBase configuration (for region servers) from HBase admin page?

[gabriela montiel]

Hi all,

We have set up an HBase cluster with 10 region nodes. We modified the 
default configurations to handle bucket cache in the hbase-site.xml (for 
all region servers) as follows:

  <property>
    <name>hbase.regionserver.handler.count</name>
    <value>40</value>
  </property>
  <property>
    <name>hbase.bucketcache.ioengine</name>
    <value>offheap</value>
  </property>
  <property>
<name>hbase.bucketcache.percentage.in.combinedcache</name>
    <value>0.8</value>
  </property>
  <property>
    <name>hbase.bucketcache.size</name>
    <value>40000</value>
  </property>

However, when we access the HBase configuration page on the HBase Web 
admin, we are not able to see the updated configurations, even for the 
ones not related to bucket cache:

<property><name>hbase.regionserver.handler.count</name><value>*30*</value><source>hbase-site.xml</source></property>


Can you give us a hint on why the configurations are not seen in the 
HBase configuration site, and how we can check out the HBase 
configuration for all region servers?

Thanks,

Gaby
