[CARBONDATA-3119] Fixing the getOrCreateCarbonSession method parameter to an empty string Fixing the getOrCreateCarbonSession method parameter to an empty string causes the select table data to be empty problem: When create carbonSession in this way: [val carbon = SparkSession.builder().config(sc.getConf).getOrCreateCarbonSession("")],The prompt can be created successfully, with no exceptions thrown during the process, but ultimately [carbon.sql("SELECT * FROM TABLE").show()] is empty. cause: [carbon.sql("SELECT * FROM TABLE").show()] is empty. solution: Increases the null or empty judgment of getOrCreateCarbonSession method parameters[storePath,metaStorePath] This closes #2961
