Wilfred Spiegelenburg commented on YARN-8373:
---------------------------------------------
{quote}1. Javadoc still says "PriorityQueue": @return sorted list in the form
of a PriorityQueue
{quote}
fixed, I thought I had changed them all.
{quote}2. Since we're using a set, maybe it's worthwile to rename the variable
"sortedList" to something else and also change the "list" word in the Javadoc.
{quote}
renamed to set
