    Function to validate the schema of the state store and maybe evolve it if needed.

    Function to validate the schema of the state store and maybe evolve it if needed. We also verify for binary inequality columns in the schema and disallow them. We then perform key and value schema validation. Depending on the passed configs, a warning might be logged or an exception might be thrown if the schema is not compatible.

    stateInfo

    - StatefulOperatorStateInfo containing the state store information

    hadoopConf

    - Hadoop configuration

    newStateSchema

    - Array of new schema for state store column families

    sessionState

    - session state used to retrieve session config

    stateSchemaVersion

    - version of the state schema to be used

    extraOptions

    - any extra options to be passed for StateStoreConf creation

    storeName

    - optional state store name

    newSchemaFilePath

    - optional path to the destination schema file. Needed for schema version 3

    returns

    - StateSchemaValidationResult containing the result of the schema validation
