HADOOP_OPTS isn't applied for Task JVMs.

For Task JVMs, set "mapred.child.java.opts" in mapred-site.xml (Or via
Configuration for per-job tuning), to the opts string you want it to
have. For example "-Xmx200m -Dsomesysprop=abc".
thanks!

hi all,

is it normal that HADOOP_OPTS are not passed to the actual tasks (ie the
java processes running as child of tasktracker)? the tasktracker process
uses them correctly.

is there a way to set general java options for each started task?


many thanks,

stijn
