== HistoryServerArguments

HistoryServerArguments is the command-line parser for the index.md[History Server].

When HistoryServerArguments is executed with a single command-line parameter it is assumed to be the event logs directory.

$ ./sbin/start-history-server.sh /tmp/spark-events

This is however deprecated since Spark 1.1.0 and you should see the following WARN message in the logs:

WARN HistoryServerArguments: Setting log directory through the command line is deprecated as of Spark 1.1.0. Please set this through spark.history.fs.logDirectory instead.

The same WARN message shows up for --dir and -d command-line options.

--properties-file [propertiesFile] command-line option specifies the file with the custom spark-properties.md[Spark properties].

NOTE: When not specified explicitly, History Server uses the default configuration file, i.e. spark-properties.md#spark-defaults-conf[spark-defaults.conf].

[TIP]

Enable WARN logging level for org.apache.spark.deploy.history.HistoryServerArguments logger to see what happens inside.

Add the following line to conf/log4j.properties:

log4j.logger.org.apache.spark.deploy.history.HistoryServerArguments=WARN

Refer to spark-logging.md[Logging].
