Configure Apache Phoenix
To configure Phoenix, complete the following steps:
- Add the following property to the - /etc/hbase/hbase-site.xmlfile 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/confon 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.dirproperty on- hbase-site.xmldoes not exist, create that directory with adequate permissions.
- Set the following porperty 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 RegionServers. 
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
