Chang Zhichao updated HADOOP-15892:
-----------------------------------
Description:
I am try using hadoop distcp command to copy a file (000079_0) to a directory
(target_directory/part_date=2018-10-28/), and the directory is not exist, like
this
{code:java}
$ hadoop fs -ls /user/hive/warehouse/migration_chang.db/target_directory/
$
$ hadoop distcp
hdfs://sdg/user/hive/warehouse/migration_chang.db/source_directory/part_date=2018-10-28/000079_0
hdfs://sdg/user/hive/warehouse/migration_chang.db/target_directory/part_date=2018-10-28/
{code}
It will copy the source file '000079_0' to a file called "part_date=2018-10-28".
{code:java}
$ hadoop fs -ls /user/hive/warehouse/migration_chang.db/target_directory/
Found 1 items
-rw-r--r-- 3 hadoop supergroup 353024605 2018-10-31 19:51
/user/hive/warehouse/migration_chang.db/snda_game_user_profile_mid_5/part_date=2018-10-28{code}
I think it is confusing, and better way is remind error like " No such
directory" .('hadoop fs -cp' command or Linux 'cp' command do like this way.)
