Configure Apache Phoenix

To configure Apache Phoenix, complete the following steps:

Add the following property to the /etc/hbase/hbase-site.xml file on all HBase nodes, the MasterServer, and all RegionServers to prevent deadlocks from occurring during maintenance on global indexes:
```
<property>
  <name>hbase.regionserver.wal.codec</name>
  <value>org.apache.hadoop.hbase.regionserver.wal.IndexedWALEditCodec</value>
</property>
```

To enable user-defined functions, configure the following property in /etc/hbase/conf on all Hbase nodes.

<property>
 <name>phoenix.functions.allowUserDefinedFunctions</name>
 <value>true</value>
 <description>enable UDF functions</description>
</property>

Ensure the client side hbase-site.xml matches the server side configuration.
If the folder specified in hbase.tmp.dir property on hbase-site.xml does not exist, create that directory with adequate permissions.

Set the following property in the hbase-site.xml file for all RegionServers, but not on the client side:

<property>
  <name>hbase.rpc.controllerfactory.class</name>
  <value>org.apache.hadoop.hbase.ipc.controller.ServerRpcControllerFactory</value>
</property>

Restart the HBase Master and Region Servers.

Configuring Phoenix to Run in a Secure Cluster

Perform the following additional steps to configure Phoenix to run in a secure Hadoop cluster:

To link the HBase configuration file with the Phoenix libraries:
ln -sf HBASE_CONFIG_DIR/hbase-site.xml PHOENIX_HOME/bin/hbase-site.xml
To link the Hadoop configuration file with the Phoenix libraries:
ln -sf HADOOP_CONFIG_DIR/core-site.xml PHOENIX_HOME/bin/core-site.xml

	Note
	When running the psql.py and sqlline.py Phoenix scripts in secure mode, you can safely ignore the following warnings.

14/04/19 00:56:24 WARN util.NativeCodeLoader:
