error in pushing parsed squid to zookeeper

[#1]

Hi,

I am using metron 0.3.0 quick dev setup and trying to configure squid feed.

this command is being used:

[root@node1 vagrant]# /usr/metron/$METRON_VERSION/bin/zk_load_configs.sh --mode PUSH -i /usr/metron/$METRON_VERSION/config/zookeeper -z $ZOOKEEPER_HOST:2181

and I am receiving following java error:

log4j:WARN No appenders could be found for logger (org.apache.curator.framework.imps.CuratorFrameworkImpl).

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 identified the reason behind same. i was having incomplete .json file indie /parser folder. When this incomplete .json was removed and same command was executed, it ran with no error.
