Transport exception
I am trying to import happybase, but the following error appears when connecting. I have a Hadoop pseudo-domain cluster and Hbase is already running. The version of the installed components is as follows: Hadoop version - 1.0.4 Hbase version - 0.94.4 happybase -0.4
Can anyone take a look at the below exceptions and let me know if any special tweaks or any recommendations to fix this.
Thank.

The trift server must be up and running. You also need to open your connection:
nohup hbase thrift start &
Open a Python connection before using:
connection.open()
Example:
#!/usr/bin/python
import happybase
connection = happybase.Connection('localhost', autoconnect=False)
connection.open()
