Hadoop distcp tool fails if file path contains special characters + & !
-----------------------------------------------------------------------

                 Key: HADOOP-3768
                 URL: https://issues.apache.org/jira/browse/HADOOP-3768
             Project: Hadoop Core
          Issue Type: Bug
    Affects Versions: 0.17.2, 0.18.0
            Reporter: Viraj Bhat


Copying folders containing + & ! characters between hdfs (using hftp) does not work in
distcp

For example: 
Copying  folder "string1+string2"  at "namenode.address.com", hftp port myport to "/myotherhome/folder"
on "myothermachine" does not work 

myothermachine prompt>>> hadoop --config ~/mycluster/ distcp  "hftp://namenode.address.com:myport/myhome/dir/string1+string2"
 /myotherhome/folder/
