Chang Zhichao updated HADOOP-15892:
-----------------------------------
Description:
I am try using hadoop distcp command to 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 " No such file or
directory" .('hadoop fs -cp' command or Linux 'cp' command do like this way.)
