Logging messages twice in Stratos Controller log files
Hi all,
Found that some messages are logged twice in SC log files, and reason being
there are some misconfiguration in log4j.properties file.
In current log4j.properties file we have following,
log4j.rootLogger=INFO, CARBON_CONSOLE, CARBON_LOGFILE, CARBON_MEMORY
log4j.logger.org.apache=INFO, CARBON_LOGFILE, CARBON_MEMORY
which means, CARBON_LOGFILE appender is added (explicitly) to "org.apache"
logger, and also the same appender is inherited from the root logger, hence
"org.apache" logger having two appenders, but both point to the same log
file.
removing CARBON_LOGFILE (and CARBON_MEMORY) appenders from "org.apache"
logger solve the problem.
Thanks
Sajith

Hi Sajith,
There are jiras created for this which are in resolved state since
duplicate logs did not appear in released M2 AMI.
Touched, not typed. Erroneous words are a feature, not a typo.
