If you want to connect to HBase running on a cluster, you'll need to follow the next step.
### Export HBASE_HOME
In **conf/zeppelin-env.sh**, export `HBASE_HOME` environment variable with your HBase installation path. This ensures `hbase-site.xml` can be loaded.
for example
```bash
export HBASE_HOME=/usr/lib/hbase
```
or, when running with CDH
```bash
export HBASE_HOME="/opt/cloudera/parcels/CDH/lib/hbase"
```
You can optionally export `HBASE_CONF_DIR` instead of `HBASE_HOME` should you have custom HBase configurations.
## Enabling the HBase Shell Interpreter
In a notebook, to enable the **HBase Shell** interpreter, click the **Gear** icon and select **HBase Shell**.
