| # Job History Server specific parameters |
| ### |
| |
| # Specify the max heapsize for the JobHistoryServer. If no units are |
| # given, it will be assumed to be in MB. |
| # This value will be overridden by an Xmx setting specified in HADOOP_OPTS, |
| # and/or MAPRED_HISTORYSERVER_OPTS. |
| # Default is the same as HADOOP_HEAPSIZE_MAX. |
| #export HADOOP_JOB_HISTORYSERVER_HEAPSIZE= |
| |
| # Specify the JVM options to be used when starting the HistoryServer. |
| # These options will be appended to the options specified as HADOOP_OPTS |
| # and therefore may override any similar flags set in HADOOP_OPTS |
| #export MAPRED_HISTORYSERVER_OPTS= |
| |
| # Specify the log4j settings for the JobHistoryServer |
| # Java property: hadoop.root.logger |
| #export HADOOP_JHS_LOGGER=INFO,RFA |
