      Description

      I install with the rpm on Centos7 (rpm -ivh pxf*.rpm).
      I start the pxf service.There is no debug logs. I need the debug logs as help me to understand pxf service.
      #vim pxf-log4j.properties

      # log to a rolling file
      log4j.rootLogger=DEBUG, ROLLINGFILE
      
      # uncomment to see DEBUG messages from PXF service
      log4j.logger.org.apache.hawq.pxf=DEBUG
      
      

      #less /var/log/pxf/catalina.out
