I upgraded my elasticsearch node from 1.5.1 to 1.7.3.
Logging.yml file has not changed.
But i dont see any new records in elasticsearch.log since upgrade.
When starting elasticsearch daemon, this message appears:
log4j:WARN No appenders could be found for logger (common).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.
I also copied elasticsearch.yml and logging.yml in $ES_HOME/config/ folder.
This did not help.
How can i see my log messages?
