Installing the MapR Client on Ubuntu

This section describes how to install the MapR client on Ubuntu.

Remove any previous MapR client software.

You can use dpkg --list | grep mapr to get a list of installed MapR packages, then type the packages separated by spaces after the dpkg -r command. Example: dpkg -l | grep mapr.
```
dpkg -r mapr-core mapr-fileserver 
```
Update your Ubuntu repositories. For example:
```
apt-get update
```
Run the following command to install the MapR client:
```
apt-get install mapr-client
```
To use this client with a secure cluster or clusters, copy the ssl_truststore file from the /opt/mapr/conf directory on the cluster to the /opt/mapr/conf directory on the client.
If this client will connect to multiple clusters, merge the ssl_truststore files with the /opt/mapr/server/manageSSLKeys.sh tool.
Run configure.sh to configure the client. In the following examples, the -N parameter specifies the cluster name, the -c (lowercase) parameter specifies a client configuration, the -secure parameter is added if the cluster is secure, the -C (uppercase) parameter specifies the CLDB nodes, and the -HS parameter specifies the HistoryServer node. To ensure that the client can connect in the event of a CLDB node failure, all CLDB nodes are specified. For more information about the syntax, parameters, and behavior of configure.sh, see configure.sh.
Secure cluster example
```
/opt/mapr/server/configure.sh -N my.cluster.com -c -secure -C mynode01:7222,mynode02:7222,mynode03:7222 -HS mynode02
```
Non-secure cluster example
```
/opt/mapr/server/configure.sh -N my.cluster.com -c -C mynode01:7222,mynode02:7222,mynode03:7222 -HS mynode02
```
NOTE
If the cluster was configured with a cluster-admin user:group that is different from the default mapr:mapr value, you must include options to specify the cluster-admin user and group information when you run configure.sh to configure the client.
If the cluster-admin user ID is present on the client node, include these options:
- -u
- -g
If the cluster-admin user ID is not present on the client node, include these options:
- -u
- -g
- --create-user | -a
- -U
- -G
At the end of the client installation, run the maprlogin password command to create a valid ticket to connect to the cluster.
