Connection

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

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.

static check_conn()[source]
static cluster_is_up(conn)[source]

Determine if an H2O cluster is up or not :param conn: An H2OConnection object containing the IP address and port of the server running H2O. :return: TRUE if the cluster is up; FALSE otherwise
