[jira] Commented: (HADOOP-6239) Command-line for append

    [ https://issues.apache.org/jira/browse/HADOOP-6239?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13003128#comment-13003128 ] 

Yanbo Liang commented on HADOOP-6239:
-------------------------------------

Maybe append on a file mostly used by API rather than command-line such as HBase log/transaction files and Facebook Scribe.

> Once append is implemented in hdfs, it would be nice if users can append files from a command-line. 
> Either have a separate 'append' command or add '-append' option for 'put' and 'cp'
> Like,  
> {noformat}
> % cat mylocalfile  | hadoop dfs -put -append - /user/knoguchi/myfile    ('-' for stdin)
> % hadoop dfs -cp -append myhdfsfile1 myhdfsfile2  
> {noformat}
