Install and configure Apache Phoenix on Cloudera Hadoop CDH5



          Apache Phoenix is a relational database layer over HBase delivered as a client-embedded JDBC driver targeting low latency queries over HBase data. Apache Phoenix takes your SQL query, compiles it into a series of HBase scans, and orchestrates the running of those scans to produce regular JDBC result sets. The table metadata is stored in an HBase table and versioned, such that snapshot queries over prior versions will automatically use the correct schema. Direct use of the HBase API, along with coprocessors and custom filters, results in performance on the order of milliseconds for small queries, or seconds for tens of millions of rows.

Step 1: Download Latest version of Phoenix using command given below

Step 2: Extract the downloaded tar file to convenient location

[root@maniadmin ~]# tar -zxvf phoenix-4.3.1-bin.tar.gz
phoenix-4.3.1-bin/bin/hadoop-metrics2-phoenix.properties
-
-
phoenix-4.3.1-bin/examples/WEB_STAT.sql

Step 3: Copy phoenix-4.3.1-server.jar to hbase libs on each reagion server and master server


On master server you should copy “phoenix-4.3.1-server.jar” at “/opt/cloudera/parcels/CDH-5.3.0-1.cdh5.3.0.p0.30/lib/hbase/lib/” location


On Hbase region server you should copy “phoenix-4.3.1-server.jar” at /opt/cloudera/parcels/CDH-5.3.0-1.cdh5.3.0.p0.30/lib/hbase/lib/ location


Step 4: Copy phoenix-4.3.1-client.jar to each Hbase region server

Please make sure to have phoenix-4.3.1-client.jar at /opt/cloudera/parcels/CDH-5.3.0-1.cdh5.3.0.p0.30/lib/hbase/lib/ on each region sever.


Step 5: Restart hbase services via Cloudera manager

Step 6: Testing – Goto extracted_dir/bin and run below command
