6. def checkAndUpdateConf(conf: H2OConf): H2OConf

   

   Check Spark and H2O environment, update it if necessary and and warn about possible problems.

   Check Spark and H2O environment, update it if necessary and and warn about possible problems.

   This method checks the environments for generic configuration which does not depend on particular backend used In order to check the configuration for specific backend, method checkAndUpdateConf on particular backend has to be called.

   This method has to be called at the start of each method which override this one

   conf

   H2O Configuration to check

   returns

   checked and updated configuration
