Allow to configure root logging level using system properties. Ex. -Des.logger.level=DEBUG . Defaults to INFO as before. 2013-08-15 14:35:23 +02:00			`# you can override this using by setting a system property, for example -Des.logger.level=DEBUG`

reafactor how actions handle failures, better response when non active shards exists, also, default logging to have action set to DEBUG so exceptions in actions are logged in the server 2010-04-07 01:54:33 +03:00			`# log action execution errors for easier debugging`
more work on reusing work node level data, now when recovering from peers 2010-06-24 15:34:02 +03:00			`action: DEBUG`

Fix example in logging daily rotate configuration PR #8464 come with a bug in the example provided. First, the current log file is not compressed so it should not end with `.gz`. Second, conversion pattern was removing all the log content but was printing only the log date. Then, the current log filename was hardcoded to `elasticsearch` instead of the cluster name. 2014-11-19 15:49:37 +01:00			`#file: ${path.logs}/${cluster.name}.log`
