James Taylor commented on PHOENIX-3123:
---------------------------------------

Thanks for the doc updates, [~rajeshbabu]. The release note changes look good, but would you mind making your on top of the patch that Josh did so we can commit both together without merge conflicts?

For the changes to secondary_indexing.md, I'd recommend changing this:
{code}
+Prior to 4.8.0 version Local indexing requires following 3 special configurations to ensure data table and local index regions co-location but 4.8.0 onwords we don't need any special configurations for local indexes.
{code}
to this:
{code}
+From Phoenix 4.8.0 onward, no configuration changes are required to use local indexing. In Phoenix 4.7 and below, the following configuration changes are required to the server-side hbase-site.xml on the master and regions server nodes:
<property>
  <name>hbase.master.loadbalancer.class</name>
  <value>org.apache.phoenix.hbase.index.balancer.IndexLoadBalancer</value>
</property>
<property>
  <name>hbase.coprocessor.master.classes</name>
  <value>org.apache.phoenix.hbase.index.master.IndexMasterObserver</value>
</property>
<property>
  <name>hbase.coprocessor.regionserver.classes</name>
  <value>org.apache.hadoop.hbase.regionserver.LocalIndexMerger</value>
</property>
{code}
