Stephen Chu commented on HADOOP-11277:
--------------------------------------
Yeah, in typical code 1 == true and 0 == false, but the Hadoop commands follow
the unix exit code conventions, where 0 means the command was successful and
non-zero means otherwise.
In this scenario, when we run {{hadoop fs -test -e}} on a file that exists,
then the exit code is 0, meaning that the existence test ran successfully.
> hdfs dfs test command "returning 0 if true." instead of what should be
> "returning 1 if true."
