Thanks the patch! Almost perfect. But one minor comment. See it below.

Please, print the warning on each duplicate only once. Now if I use the same name
N >= 2 times, the warning for the name is printed N - 1 times.
Example:
name1, name1, name1, name1
In the log I see:
Duplicate replica.name found: name1
Duplicate replica.name found: name1
Duplicate replica.name found: name1
Must be:
Duplicate replica.name found: name1
For example, you can store in 'names' not booleans, but count of name
duplicates. And print the warning only when the count is 2.
