Software Requirements

Prior to installing HCP, ensure that you meet the software specifications required by HCP.

The host that you choose to use to deploy Apache Metron must have the following software tools installed:

Hadoop (HDP 2.5 or HDP 2.6 recommended)

The following are the required components for HDP 2.5.x and HDP 2.6.x:
- Apache Hadoop

  Note
  
  Supervisor, Kafka Broker, and the HBase client must be installed on the Metron Install Host.
To use the PCAP query user interface, you must perform the following:
- Install Wireshark.
  For example, for CentOS, use the following command:
```

```
- Add a Metron user to the Wireshark group.
  For example, for CentOS, use the following command:
