hdfsConnect()
Supported by libMapRClient for hadoop-2.x
Connects to a file system cluster.
If a connection to the cluster in which the remote host is located already exists, the functions return a handle to this existing connection.
If a connection to the cluster does not already exist, the functions return a handle to a new connection instance.
Note that if default is used for the
host parameter, this means connect to the first
cluster listed in the
MAPR_HOME/conf/mapr-clusters.conf file on the
client.
For more information about connections, see Establishing Connections to file system.
