Commit 949660 broke FileUtil.copyMerge
--------------------------------------
Key: HADOOP-7135
URL: https://issues.apache.org/jira/browse/HADOOP-7135
Project: Hadoop Common
Issue Type: Bug
Components: fs
Affects Versions: 0.21.0
Reporter: Jeffrey Gerard
Looking at
http://svn.apache.org/viewvc/hadoop/common/branches/branch-0.21/src/java/org/apache/hadoop/fs/FileUtil.java?r1=949659&r2=949660&;
it seems this commit broke FileUtil.copyMerge by omitting NOT operator.
copyMerge only makes sense if srcDir is a directory.
Should be
if (!srcFS.getFileStatus(srcDir).isDirectory())
return false;
