Package org.apache.sysds.conf

Class ConfigurationManager

  • public class ConfigurationManager
extends Object
    Singleton for accessing the parsed and merged system configuration. NOTE: parallel execution of multiple DML scripts (in the same JVM) with different configurations would require changes/extensions of this class.

      • getCachedJobConf

        public static org.apache.hadoop.mapred.JobConf getCachedJobConf()
        Returns a cached JobConf object, intended for global use by all operations with read-only access to job conf. This prevents to read the hadoop conf files over and over again from classpath. However,
        Returns:
        the cached JobConf

      • setCachedJobConf

        public static void setCachedJobConf​(org.apache.hadoop.mapred.JobConf job)

      • setGlobalConfig

        public static void setGlobalConfig​(DMLConfig conf)
        Sets a global configuration as a basis for any thread-local configurations. NOTE: This global configuration should never be accessed directly but only through its thread-local derivatives.
        Parameters:
        conf - the configuration

      • setLocalConfig

        public static void setLocalConfig​(DMLConfig conf)
        Sets the current thread-local dml configuration to the given config.
        Parameters:
        conf - the configuration

      • getDMLConfig

        public static DMLConfig getDMLConfig()
        Gets the current thread-local dml configuration.
        Returns:
        the dml configuration

      • setGlobalConfig

        public static void setGlobalConfig​(CompilerConfig conf)

      • setLocalConfig

        public static void setLocalConfig​(CompilerConfig conf)
        Sets the current thread-local compiler configuration to the given config.
        Parameters:
        conf - the compiler configuration

      • clearLocalConfigs

        public static void clearLocalConfigs()
        Removes the thread-local dml and compiler configurations, leading to a reinitialization on the next get unless set in between.

      • getCompilerConfig

        public static CompilerConfig getCompilerConfig()
        Gets the current thread-local compiler configuration.
        Returns:
        the compiler configuration

      • getCompilerConfigFlag

        public static boolean getCompilerConfigFlag​(CompilerConfig.ConfigType key)
        Get a boolean compiler config in a robust manner, returning false if config not existing.
        Parameters:
        key - config type
        Returns:
        compiler config flag
