Hi,how can empty output files (no "output.collect()" called) be avoided in Hadoop 0.20.203?
The documentation suggests using LazyOutputFormat: http://hadoop.apache.org/mapreduce/docs/current/mapred_tutorial.html#Lazy+Output+Creation However, it seems as if it exists beginning from 0.21.0 only: http://hadoop.apache.org/mapreduce/docs/current/api/org/apache/hadoop/mapreduce/lib/output/LazyOutputFormat.html I couldn't find it in Hadoop 0.20.203. Best regards, Katja Müller
