Hello,
What is the best way to pass job configuration parameter to class like GroupingComparator which is instantiated by hadoop. I know there is setup method in map class and probably I can initialize some static variable in setup and use it in GroupingComparator, not sure that is correct (not sure there is guarantee that GroupingComparator will be instantiated after first call of map on this node) But what is preferred pattern for the case? Maybe there is some unified way to access job config from anywhere? Thanks! Sergey.
