Subject [jira] [Updated] (HADOOP-15892) hadoop distcp command fail without reminder
Date Wed, 31 Oct 2018 11:42:00 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-15892?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

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.)

 

 

  was:
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" .
