Devaraj Das updated HADOOP-4362:
--------------------------------
Component/s: (was: contrib/streaming)
dfs
Peeyush offline got this stack trace when he tried to run wordcount. Looks like
a DFS issue - maybe HADOOP-4351. If dfs folks think so, please mark this bug as
a duplicate.
hadoop jar hadoop-examples.jar wordcount -m 8 -r 2
