Hi Chung, >From my short experience on Hive this may happen due to various reasons. To find the real root cause you may need to dig in to hadoop tasktracker logs and see what's present there. Also have a look at the task log from the web UI (it gets printed to the console at the start of the Hive job) and it may reveal the real cause for your issue. (e.g: I once encountered this error due to one of my custom mapper scripts no being included properly).
