[jira] [Created] (HADOOP-15892) hadoop distcp command fail without reminder

Chang Zhichao created HADOOP-15892:
--------------------------------------

             Summary:  hadoop distcp command fail without reminder
                 Key: HADOOP-15892
                 URL: https://issues.apache.org/jira/browse/HADOOP-15892
             Project: Hadoop Common
          Issue Type: Bug
          Components: fs
    Affects Versions: 2.5.0
            Reporter: Chang Zhichao


hadoop distcp command copy a file to a directory, like this
{code:java}
hadoop distcp  hdfs://sdg/user/hive/warehouse/migration_chang.db/snda_game_user_profile_mid_3/part_date=2018-10-28/000079_0   hdfs://sdg/user/hive/warehouse/migration_chang.db/snda_game_user_profile_mid_5/part_date=2018-10-28/
{code}
It will copy the source file '000079_0' to a file called "part_date=2018-10-28".

I think it is confusing and better way is remind error like 'hadoop fs -cp' command: " No such file or directory" .
