Change in logging framework from log4j to logback for zookeeper in Global Mailbox v6122 and higher

With out of box settings of the newer logging framework, zookeeper logs are written in a file named Zookeeper.out and this file does not roll over. In order to get the logs written to a different file, i.e. Zookeeper.log, and enable the rolling of log files, please make the below changes in the logback.xml file in <GlobalMailbox Install>/zookeeper/conf directory path:

uncomment the section of code in the logback.xml. The section starts on line 50 and ends on line 65.

Starting line:

<!--appender name="ROLLINGFILE" class="ch.qos.logback.core.rolling.RollingFileAppender">

Ending line:

</appender-->

Edit below line:

<property name="zookeeper.log.file" value="zookeeper.log" />

And change the maxfilesize value to 1 MB(you can give the size as per your requirement), like this:

<property name="zookeeper.log.maxfilesize" value="1MB" />

Provide the absolute path <property name="zookeeper.log.dir" value="<GM Install location>/zookeeper/logs" />

Add the ROLLINGFILE at the root level and

<root level="INFO">

  <appender-ref ref="CONSOLE" />

  <appender-ref ref="ROLLINGFILE" />

 </root>

Post this, restart the zookeeper using the scripts stopGMCoordinate.sh to stop and startGMCoordinate.sh to start from <GlobalMailbox Install>/MailboxUtilities/bin/ directory.

Please note,  post these changes, zookeeper will still write the same logs in Zookeeper.out as well along with the new log file(zookeeper.log) name configured in logback.xml file.
