Configure HBase for use with Phoenix

Before you start using Phoenix with HBase, you must configure HBase to recognize Phoenix operations.

Configure the following HBase properties using Cloudera Manager:

Go to the HBase service.
Click the Configuration tab.
Select Scope > RegionServer.
Select Category > Advanced.
Locate WAL Codec class property or search for hbase.regionserver.wal.codec.
Click View as XML and add the following property value:
```
org.apache.hadoop.hbase.regionserver.wal.IndexedWALEditCodec
```
Set the HBase Service Advanced Configuration Snippet and HBase Client Advanced Configuration Snippet properties to enable user-defined functions. Locate the property or search for HBase Service Advanced Configuration Snippet (Safety Valve) for hbase-site.xml and HBase Client Advanced Configuration Snippet (Safety Valve) for hbase-site.xml.
Add the following property value:
```
<property>
  <name>phoenix.functions.allowUserDefinedFunctions</name>
  <value>true</value>
</property>
```
Enter a Reason for change, and then click Save Changes to commit the changes.
Restart the role and service when Cloudera Manager prompts you to restart.
