> It is legal for long values in the config file to have an L or for float values to have
an f.  For example, the default value for hive.compactor.check.interval was 300L.  As part
of HIVE-5799, many long values were converted to TimeUnit.  Attempts to read these values
now throw "java.lang.IllegalArgumentException: Invalid time unit l"
> We need to change this to ignore the L or f, so that users existing config files don't
break.  I propose to do this by changing HiveConf.unitFor to detect the L or f and interpret
it to mean the default time unit.
