-----------------------------------
Summary: Improve error message when hadoop archive output path
already exists
Key: HADOOP-9723
URL: https://issues.apache.org/jira/browse/HADOOP-9723
Project: Hadoop Common
Issue Type: Improvement
Affects Versions: 2.0.4-alpha, 3.0.0
Reporter: Stephen Chu
Priority: Trivial
When creating a hadoop archive and specifying an output path of an already
existing file, we get an "Invalid Output" error message.
{code}
[schu@hdfs-vanilla-1 ~]$ hadoop archive -archiveName foo.har -p /user/schu
testDir1 /user/schu
Invalid Output: /user/schu/foo.har
{code}
This error can be improved to tell users immediately that the output path
already exists.
