Todd Lipcon commented on MAPREDUCE-2550:
----------------------------------------
Do we need the following export?
+export HADOOP_PREFIX="${HADOOP_PREFIX:-$bin/..}"
the sourcing of {{hadoop-config.sh}} should set this to point at COMMON_HOME in
dev env or the appropriate prefix in an installed env, right?
> bin/mapred no longer works from a source checkout
