Konstantin Boudnik commented on MAPREDUCE-1933:
-----------------------------------------------
bq. prop.put("mapred.local.dir",
"/grid/0/dev/tmp/mapred/mapred-local,/grid/1/dev/tmp/mapred/mapred-local,/grid/2/dev/tmp/mapred/mapred-local,/grid/3/dev/tmp/mapred/mapred-local");
Absolutely, besides this particular parameter should be set by a normal MR
config already.
Also, please don't use string literals for configuration parameters. There was
a significant effort in 0.21 to have all configuration keys refactored to named
constants. Use them instead.
