Tsz Wo (Nicholas), SZE updated HADOOP-5620:
-------------------------------------------
Hadoop Flags: [Incompatible change]
- Should discp also preserve modification times of directories? Otherwise, the
new -t option seems confusing.
- It might be better to get mtime and atime inside the if-statement
{code}
if ( preserve_status && preseved.contains(FileAttribute.TIMES)) {
...
}
{code}
since srcstat remains unchanged in the method.
- Marking this as an incompatible change because it change the meaning of -p.
> discp can preserve modification times of files
