REST Interface¶

An H2OConnection represents the latest active handle to a cloud. No more than a single H2OConnection object will be active at any one time.

class h2o.connection.H2OConnection(ip='localhost', port=54321, size=1, start_h2o=False, enable_assertions=False, license=None, max_mem_size_GB=None, min_mem_size_GB=None, ice_root=None, strict_version_check=True, proxies=None)[source]¶

Bases: object

H2OConnection is a class that represents a connection to the H2O cluster. It is specified by an IP address and a port number.

Objects of type H2OConnection are not instantiated directly!

This class contains static methods for performing the common REST methods GET, POST, and DELETE.

cluster_is_up(conn)	Determine if an H2O cluster is up or not
