Joep Rottinghuis commented on PIG-3929:
---------------------------------------

Why not simply default this to hadoop.tmp.dir ?
True that hadoop.tmp.dir often has variables in it itself (for example 
/tmp/hadoop-${user}) however, if pig.temp.dir cannot directly refer to 
hadoop.tmp.dir then both need to be kept in sync by hand ?

> pig.temp.dir should allow to substitute vars as hadoop configuration does
