Configuring HBase for Phoenix
To enable global indexing and local indexing in Phoenix, complete the following steps.
Add the following properties to the hbase-site.xml file on all HBase nodes, the Master Server, and all Region servers.
Set hbase.defaults.for.version.skip to true:
<property> <name>hbase.defaults.for.version.skip</name> <value>true</value> </property>
Set hbase.regionserver.wal.codec to enable custom write-ahead log ("WAL") edits to be written as follows:
<property> <name>hbase.regionserver.wal.codec</name> <value>org.apache.hadoop.hbase.regionserver.wal.IndexedWALEditCodec</value> </property>
Set the following properties to prevent deadlocks from occurring during index maintenance for global indexes by ensuring index updates are processed with a higher priority than data updates and also to prevent deadlocks by ensuring metadata rpc calls are processed with a higher priority than data rpc calls.
<property> <name>hbase.region.server.rpc.scheduler.factory.class</name> <value>org.apache.hadoop.hbase.ipc.PhoenixRpcSchedulerFactory</value> <description>Factory to create the Phoenix RPC Scheduler that uses separate queues for index and metadata updates</description> </property> <property> <name>hbase.rpc.controllerfactory.class</name> <value>org.apache.hadoop.hbase.ipc.controller.ServerRpcControllerFactory</value> <description>Factory to create the Phoenix RPC Scheduler that uses separate queues for index and metadata updates</description> </property>
To enable user-defined functions, configure the following property in
hbase-site.xml
on all Hbase nodes.<property> <name>phoenix.functions.allowUserDefinedFunctions</name> <value>true</value> <description>enable UDF functions</description> </property>
Warning The local indexing feature is a technical preview and considered under development. Do not use this feature in your production systems. If you have questions regarding this feature, contact Support by logging a case on our Hortonworks Support Portal.
Restart the HBase Master and Region Servers.
