Tom White commented on HADOOP-7098:
-----------------------------------
+1 The lack of a HADOOP_TASKTRACKER_OPTS definition looks like an oversight
(these variables were introduced in HADOOP-2551). HADOOP_TASKTRACKER_OPTS is
already honoured by bin/mapred, so no changes are needed there.
Bernd, have you tested this manually? There's currently no easy way to write an
automated test for this change.
> tasktracker property not set in conf/hadoop-env.sh
