Tsz Wo (Nicholas), SZE commented on HADOOP-8173:
------------------------------------------------
I tested it with the following:
{code}
public static void main(String[] args) throws IOException {
File f = new File("a.txt");
final BufferedReader in = new BufferedReader(new FileReader(f));
for(String line; (line = in.readLine()) != null;) {
testPattern(line);
}
}
static String testPattern(String s) {
System.out.print("replace " + s);
s = s.replaceAll("\\\\(.)", "$1");
System.out.println(" to " + s);
return s;
}
{code}
and the result is
{noformat}
replace foo* to foo*
replace foo\* to foo*
replace foo\\* to foo\*
replace foo\\\* to foo\*
replace foo\ to foo\
replace foo\\ to foo\
replace foo\\\ to foo\\
replace foo\** to foo**
replace foo*bar to foo*bar
replace foo\*bar to foo*bar
replace foo\\*bar to foo\*bar
replace foo\\\*bar to foo\*bar
replace foo\bar to foobar
replace foo\\bar to foo\bar
replace foo\\\bar to foo\bar
replace foo\**bar to foo**bar
replace foo*bar* to foo*bar*
replace foo\*bar\* to foo*bar*
replace foo\\*bar\\* to foo\*bar\*
replace foo\\\*bar\\\* to foo\*bar\*
replace foo\bar\ to foobar\
replace foo\\bar\\ to foo\bar\
replace foo\\\bar\\\ to foo\bar\\
replace foo\**bar\** to foo**bar**
{noformat}
Do you think that they are all expected?

> Commands that access paths with quoted metachars work correctly, however
> commands that create paths with quoted metachars leave the \ in the path.
> Ex.
> {noformat}
> fs -mkdir "foo\*bar" will create "foo\*bar" instead of "foo*bar".
> {noformat}
