No single argument constructor found for class [Ljava.lang.String;; in 'reader', line 10, column 1:

While setting up of cassandra you might face below error. I faced below error, i did workaround and identified the solution of same. I am going to provide the solutions to all of you guys, to get you out from the any severe problem.

No single argument constructor found for class [Ljava.lang.String;;  in 'reader', line 10, column 1:
   cluster_name: 'Test Cluster'

Problem:
While modification of cassandra.yaml file you might change the format of given directories

Solution:
Change directories path format as given below (it should be exactly same)

data_file_directories:
    - /cassandra/storage/data
commitlog_directory: /cassandra/storage/commitlog
saved_caches_directory: /cassandra/storage/saved_caches

Workaround
In my case i have written data_file_directories as below

data_file_directories: /cassandra/storage/data

When i change path as per given format, then it works fine for me.
