Upon checking the code here, the issue seems to be with import of 'expect' module
I tried the following changes in params.py:
L30: from resource_management.libraries.functions import expect L107: regionserver_xmn_percent = expect.expect("/configurations/hbase-env/hbase_regionserver_xmn_ratio", float) #AMBARI-15614
Now the snapshot command ran fine:
