Date Wed, 22 Apr 2009 01:16:47 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-5675?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12701348#action_12701348

Suhas Gogate commented on HADOOP-5675:
--------------------------------------

Tested the patch and here are some comments w.r.t. following output I see,

1. suggestions for counter names:  srcCount => sourceFilesCount,  fileCount => filesToCopyCount,
 byteCount => bytesToCopyCount

2. Remove white spaces between counter name and value. 

09/04/21 23:37:30 INFO tools.DistCp: srcCount = 6
09/04/21 23:37:30 INFO tools.DistCp: fileCount= 2
09/04/21 23:37:30 INFO tools.DistCp: byteCount= 341.5k
