The HPE Ezmeral Data Fabric Event Store C Client is a distribution of librdkafka that works with HPE Ezmeral Data Fabric Event Store.

For instructions on installing the MapR Client, see Installing the Data Fabric Client
For instructions on setting up the MEP repository, see Step 10: Install Ecosystem Components Manually.

Installation

As of MapR 6.0.1, the MapR C client is installed as part of the MapR Core installation and the mapr-client package installation. The MapR C client is available on Linux, Mac, and Windows operating systems.

Note: Specific installation is not required as of MapR 6.0.1!

For MapR 5.2.1 through MapR 6.0.0, the MapR C client must be installed. The MapR C client is available on Linux and Mac operating systems. As root or using sudo, install the mapr-librdkafka package on nodes where you want to run or build applications.

On Ubuntu:
```
apt-get install mapr-librdkafka
```
On RedHat/CentOS:
```
yum install mapr-librdkafka
```
On SUSE:
```
zypper install mapr-librdkafka
```
On Mac OS:
1. Download the following TAR file: https://package.mapr.com/releases/MEP/<MEP version>/<operating system>/<package>.tar.gz
2. Extract the TAR file under /opt/mapr:
```
tar -C /opt/mapr/ -zxf <librdkafka_tarFile_location>
```

Note: The mapr-librdkafka package pulls in the mapr-client as a dependency if the node does not have the mapr-client or mapr-core package installed.

Configuration

For MapR 6.0.1 and higher, use the following configuration instructions.
