Yup that makes sense. But when I tried opening that file using- hadoop fs -text /apps/hdmi-technology/b_apdpds/real-time_new/20120731/PDS_HADOOP_REALTIME_EXPORT-part-3-2
I can see my file contents there? Then what's wrong with that file? And is there any way I can fix that error in that file using some script?
