Subject [jira] Commented: (HDFS-222) Support for concatenating of files into a single file
Date Tue, 06 Oct 2009 07:58:31 GMT

    [ https://issues.apache.org/jira/browse/HDFS-222?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12762548#action_12762548
] 

dhruba borthakur commented on HDFS-222:
---------------------------------------

This is a useful feature to have.  I am guessing that there will be a few more hdfs-specific
tools that we will develop going forward. This toll currently is invoked by "bin/hadoop jar
org.apache.hdfs.tools.HDFSConcat fileA fileB". Does it make it easier to use if  this can
be "bin/hadoop hdfs -concat fileA fileB"?
