# Presto 316 Documentation

## 12.190. Release 0.54

- Restore binding for the node resource on the coordinator, which provides the state of all nodes as seen by the coordinator’s failure detector. Access `/v1/node` to see all nodes, or `/v1/node/failed` to see failed nodes.

- Prevent the Command Line Interface from hanging when the server goes away.

- Add Hive connector `hive-hadoop1` for Apache Hadoop 1.x.

- Add support for Snappy and LZ4 compression codecs for the `hive-cdh4` connector.

- Add Example HTTP connector `example-http` that reads CSV data via HTTP. The connector requires a metadata URI that returns a JSON document describing the table metadata and the CSV files to read.

  Its primary purpose is to serve as an example of how to write a connector, but it can also be used directly. Create `etc/catalog/example.properties` with the following contents to mount the `example-http` connector as the `example` catalog:

      connector.name=example-http
      metadata-uri=http://s3.amazonaws.com/presto-example/v1/example-metadata.json

- Show correct error message when a catalog or schema does not exist.

- Verify JVM requirements on startup.

- Log an error when the JVM code cache is full.

- Upgrade the embedded Discovery server to allow using non-UUID values for the `node.id` property.
