And now I am having another similar problem with translate plugin. I have been using translate filter using logstash 2.3.1 and it was working fine. like
translate {
field => "xxxx"
dictionary_path => "/yyyy/zzzz.csv"
destination => "wwww"
}
The configuration works in logstash 2.3.1, but when running with logstash 2.2.0, I got this error
The error reported is:
LogStash::Filters::Translate: Bad Syntax in dictionary file /yyyy/zzzz.csv
Combining this issue and the issue above, I cannot run using either version which has both elasticsearch and translate filter. 
As I did not see any coding change in these two plugin but dependency changes, I will appreciate any help that can pointing me to the direction to solve this problem.
