Installing Phoenix

About this task

Complete the following steps to install Phoenix:

Download the Phoenix archive file associated with the version that you want to install: http://phoenix.apache.org/download.html
Run the following command to extract the content of the archive file to a directory:
```
tar -xf phoenix-<version>-incubating.tar.gz
```
Add the phoenix-<version>-incubating-client-minimal.jar and the phoenix-core-<version>-incubating.jar files to the classpath of every HBase region server. For example, navigate to the directory where you extracted phoenix-3.0.0-incubating.tar.gz, and copy the phoenix-core-3.0.0-incubating.jar and phoenix-core-3.0.0-incubating.jar into the /opt/mapr/hbase/hbase-<version>/lib directory.

NOTE: The phoenix-core-3.0.0-incubating.jar and phoenix-core-3.0.0-incubating.jar files are located in phoenix-3.0.0-incubating/common.
Run the following command to restart all of the HBase region servers:
```
maprcli node services -hbregionserver restart -nodes <hostname>
```
Optionally, you can run the following command to verify that the Phoenix JARs were copied to the HBase classpath:
```
hbase classpath | grep 'phoenix'
```
On client-only nodes, add the phoenix-<version>-incubating-client.jar to the classpath of the Phoenix client (only for use with Hadoop 1.x). For example, copy the JAR from the following directory:
```
<phoenix installation directory>/phoenix-<version>-incubating/hadoop-1/phoenix-<version>-incubating-client.jar
```
to this directory:
```
/opt/mapr/hadoop/hadoop-<version>/lib
```

Now you can start Phoenix.
