Examples -Driver does not check first argument.
-----------------------------------------------
Key: HADOOP-4608
URL: https://issues.apache.org/jira/browse/HADOOP-4608
Project: Hadoop Core
Issue Type: Bug
Components: examples
Affects Versions: 0.18.2
Reporter: Edward J. Yoon
Assignee: Edward J. Yoon
Fix For: 0.18.3
hadoop@vldb ~/hadoop $ bin/hadoop jar hadoop-0.18.2-examples.jar
An example program must be given as the first argument.
Valid program names are:
aggregatewordcount: An Aggregate based map/reduce program that counts the words in the input files.
aggregatewordhist: An Aggregate based map/reduce program that computes the histogram of the words in the input files.
grep: A map/reduce program that counts the matches of a regex in the input.
join: A job that effects a join over sorted, equally partitioned datasets
multifilewc: A job that counts words from several files.
pentomino: A map/reduce tile laying program to find solutions to pentomino problems.
pi: A map/reduce program that estimates Pi using monte-carlo method.
randomtextwriter: A map/reduce program that writes 10GB of random textual data per node.
randomwriter: A map/reduce program that writes 10GB of random data per node.
sleep: A job that sleeps at each map and reduce task.
sort: A map/reduce program that sorts the data written by the random writer.
sudoku: A sudoku solver.
wordcount: A map/reduce program that counts the words in the input files.
java.lang.IllegalArgumentException: An example program must be given as the first argument.

Owen O'Malley updated HADOOP-4608:
----------------------------------
Resolution: Fixed
Fix Version/s: (was: 0.18.3)
(was: 0.19.1)
Hadoop Flags: [Reviewed]
Status: Resolved (was: Patch Available)
I just committed this. Thanks, Edward!
This isn't a blocker, so only applying to trunk.

Integrated in Hadoop-trunk #661 (See [http://hudson.zones.apache.org/hudson/job/Hadoop-trunk/661/])
. Don't print a stack trace when the example driver gets an
unknown program to run. (Edward Yoon via omalley)
