----------------------------------------------------------------
Key: HADOOP-7340
URL: https://issues.apache.org/jira/browse/HADOOP-7340
Project: Hadoop Common
Issue Type: Improvement
Components: fs
Affects Versions: 0.23.0
Reporter: XieXianshan
Assignee: XieXianshan
Fix For: 0.23.0
The help message for the command "hdfs dfs -help getmerge" is displayed like
this:
"-getmerge <src> <localdst> [addnl]: Get all the files in the directories
that
match the source file pattern and merge and sort them to only
one file on local fs. <src> is kept."
and the information about [addnl] option is missed,despite the fact that
[addnl] option is implemented.
Therefore,the expected message should be displayed like this:
"-getmerge <src> <localdst> [addnl]: Get all the files in the directories
that
match the source file pattern and merge and sort them to only
one file on local fs. <src> is kept.
addnl Optionally addnl can be set to enable adding a
newline
character at the end of each file."
