[Solution] Elasticsearch 0.90 insallation with .rpm and logging Errors

Problem : 

I downloaded the latest ES rpm and installed on centos. When tried running the script in foreground, i see that the logging is not enabled.

tried both /etc/init.d/elasticsearch -f and   /usr/share/elasticsearch/bin/ -f both. 

log4j:WARN No appenders could be found for logger (node).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.

and nothing gets logged.

Tried the following in vain : 

• export ES_CLASSPATH=/etc/elasticsearch/logging.yml 
• changed patch.conf, path.data in elasticsearch.yml file

But, Nothing seems to fix the logging problem

Solution:

edit /usr/share/elasticsearch/bin/elasticsearch  

give absolute paths for the home, and all files.

This file should be changed, so "any" startup of elasticsearch will work in foreground without errors

ES_JAVA_OPTS="-Des.config=/etc/elasticsearch/elasticsearch.yml -Des.path.conf=/etc/elasticsearch/ -Des.path.home=/usr/share/elasticsearch -Des.path.logs=/var/log/elasticsearch -Des.path.data=/var/lib/elasticsearch -Des.path.work=/tmp/elasticsearch -Des.path.plugins=/usr/share/elasticsearch/plugins"
