============ 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 :doc:`/installation/cli` 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: .. code-block:: none 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.
