Jan van der Lugt updated HADOOP-8415:
-------------------------------------
Description: In the org.apache.hadoop.conf.Configuration class, methods
exist to set Integers, Longs, Booleans, Floats and Strings, but methods for
Doubles are absent. Are they not there for a reason or should they be added? In
the latter case, the attached patch contains the missing functions. (was: In
the org.apache.hadoop.conf.Configuration class, methods exist to set Integers,

are the missing functions:
