@@ -21,7 +21,6 @@ Each package features a configuration file, which allows you to set the followin
 `MAX_MAP_COUNT`::         Maximum number of memory map areas a process may have. If you use `mmapfs` as index store type, make sure this is set to a high value. For more information, check the https://github.com/torvalds/linux/blob/master/Documentation/sysctl/vm.txt[linux kernel documentation] about `max_map_count`. This is set via `sysctl` before starting elasticsearch. Defaults to `65535`
 `LOG_DIR`::               Log directory, defaults to `/var/log/elasticsearch`
 `DATA_DIR`::              Data directory, defaults to `/var/lib/elasticsearch`
-`WORK_DIR`::              Work directory, defaults to `/tmp/elasticsearch`
 `CONF_DIR`::              Configuration file directory (which needs to include `elasticsearch.yml` and `logging.yml` files), defaults to `/etc/elasticsearch`
 `CONF_FILE`::             Path to configuration file, defaults to `/etc/elasticsearch/elasticsearch.yml`
 `ES_JAVA_OPTS`::          Any additional java options you may want to apply. This may be useful, if you need to set the `node.name` property, but do not want to change the `elasticsearch.yml` configuration file, because it is distributed via a provisioning system like puppet or chef. Example: `ES_JAVA_OPTS="-Des.node.name=search-01"`
