I was using logstash-1.x which processed CSV perfectly. Now upgraded LS to logstash-2.0.0 and when it process CSV i see repetition of rows. e.g.: CSV has following columns and values Col1|Col2|Col3 1|2|3 a|b|c x|y|z when logstash-2.0.0 pareses and it prcesses twice resulting query result with duplicate data e.g. Col1|Col2|Col3 1|2|3 a|b|c x|y|z 1|2|3 a|b|c x|y|z Any idea why? it works fine with LS 1.x. ---
