> Lets say you have output directory set:
> FileOutputFormat.setOutputPath(job, "/tmp/multi1/out");
> and want to place output from MultipleOutputs into /tmp/multi1/extra
> I expect following code to work:
> mos = new MultipleOutputs<Text, IntWritable>(context);
> mos.write(new Text("zrr"), value, "../extra/");
> but no Exception is throw and expected output directory /tmp/multi1/extra
> does not even exists. All data written to this output vanish without trace.
> To make it work fullpath must be used
> mos.write(new Text("zrr"), value, "/tmp/multi1/extra/");
> Output is listed in statistics from MultipleOutputs correctly:
> org.apache.hadoop.mapreduce.lib.output.MultipleOutputs
> ../gaja1/=13333 (* everything is lost *)
> /tmp/multi1/out/../ksd34/=13333 (* this using full path works
> *)
