When specifying a keyspace in the Cassandra Target with uppercase letters you may get a NullPointerException or error stating that the Keyspace cannot be found.
This is because Cassandra's case-sensitivity rules dictate that in general, everything is treated as lowercase unless double quoted.
From the Cassandra Java Driver documentation:
We expect client-facing APIs to behave like cqlsh, that is:
* - identifiers that are mixed-case or contain special characters should be quoted.
* - unquoted identifiers will be lowercased: getKeyspace("Foo") will look for a keyspace named "foo"
Thus, if you are looking to write to a table MyKeyspace.table_name you must specify it as "MyKeyspace".table_name
