I wrote some data into a file using MultipleOutputs in mappers. I can see the contents in this file using "hadoop fs -ls <file>", but its size is reported as zero by the command "hadoop fs -du <file>" or "hadoop fs -ls <file>" , as follows:
-rw-r--r-- 3 hadoop hadoop 0 2014-04-07 22:06 /test/xt/out/2014-01-20/-m-00000 BTW, when I download this file from HDFS to local file system, I can see the correct size. Why is it reported as zero size in hadoop CLI?
