Cassandra Error saving key space and does not display key areas in opscenter

Question

if I try to save a new key space, it will give me the following error.

Error saving keyspace: Call to /Cluster/keyspaces/newname timed out. 

if I want to create an existing keyspace, I get the following error

 Error saving keyspace: Keyspace names must be case-insensitively unique ("shashank" conflicts with "shashank") 

The problem is that I do not see any key in my opscenter user interface browser

One of the easiest ways to see existing clusters is to open a CQL shell on one of your nodes. Go to the bin folder in the root folder where Cassandra was installed and run "CQLSH". At this command line, you can simply enter “describe key spaces” and you will get a list of all available clusters in that cluster.

It should be noted that case sensitivity is only observed by Cassandra if you put double quotes around the name of the object. Otherwise, everything is simply converted to lowercase and compared in this way.
