Hi, All Doing HIVE-3431(https://issues.apache.org/jira/browse/HIVE-3431), I needed to define a magic word which means "this is not a path string and translate it as a temporary directory".
I think HIVE-3779 (https://issues.apache.org/jira/browse/HIVE-3779) also might need something like that. What I'm asking is, is there a convention for those magic words? If not, do we need to define it? ($hive_<KEYWORD>, for example)
