Jonathan Eagles updated HADOOP-14233:
-------------------------------------
    Description: The String in the precondition check is constructed prior to 
failure detection. Since the normal case is no error, we can gain performance 
by delaying the construction of the string until the failure is detected.

> Delay construction of PreCondition.check failure message in Configuration#set
