# Manually Install Community Connectors for Confluent Platform

This topic describes how to install community connectors that are not available from [Confluent Marketplace](https://www.confluent.io/hub/).
If a connector is not available on Confluent Marketplace, you must first obtain or build the JARs, and then install the connectors
into your Apache Kafka® installation.

#### IMPORTANT
[Confluent Marketplace](https://www.confluent.io/hub/) hosts many popular connectors developed by companies and
open source organizations and individuals. If a connector is available on Confluent Marketplace, you can skip this
topic.

In the following example, the HDFS Sink Connector is installed manually.

1. Clone the GitHub repo for the connector.
   ```bash
   git clone https://github.com/confluentinc/kafka-connect-hdfs.git
   ```
2. Navigate to your cloned repo, checkout the version you want, and build the JAR with Maven.
   You will want to checkout a released version typically. This example uses the `v3.0.1` release tag:
   ```bash
   cd kafka-connect-hdfs; git checkout v3.0.1; mvn package
   ```
3. Locate the connector’s [uber JAR or plugin directory](userguide.html#installing-kconnect-plugins),
   and copy that into one of the directories on the Kafka Connect worker’s [plugin path](userguide.html#connect_configuring_workers).
   For example, if the plugin path includes the `/usr/local/share/kafka/plugins` directory, you can use one of the following
   techniques to make the connector available as a plugin.

   If the connector were to create an uber JAR file named `kafka-connect-hdfs-3.0.1-package.jar`, you could
   copy that file into the `/usr/local/share/kafka/plugins` directory:
   ```bash
   cp target/kafka-connect-hdfs-3.0.1-package/share/java/kafka-connect-hdfs/kafka-connect-hdfs-3.0.1-package.jar /usr/local/share/kafka/plugins/
   ```

   Or, if the connector’s JARs are collected in one of the build’s `target` directories, you can copy all of these JARs into a plugin directory inside the `/usr/local/share/kafka/plugins`:
   ```bash
   mkdir -p /usr/local/share/kafka/plugins/kafka-connect-hdfs
   cp target/kafka-connect-hdfs-3.0.1-package/share/java/kafka-connect-hdfs/* /usr/local/share/kafka/plugins/kafka-connect-hdfs/
   ```
4. If you’re running Kafka Connect distributed worker processes, you must repeat these steps on all of your machines.
   Every connector must be available on all workers, since Kafka Connect will distribute the connector tasks to any of
   the workers.
