Eric Yang commented on HADOOP-7583:
-----------------------------------
Primary use case:
With explicit packaging:
* export HADOOP_*_HOME
* mvn clean package -Pdist
* run HDFS
* run mapreduce
* Test things
With implicit packaging:
* export HADOOP_*_HOME
* mvn clean package
* run HDFS
* run map reduce
* Test things
Build time are the same for both cases because the directory layout is required
to run HDFS/MR for testing.
Secondary use case, for projects that depends on Hadoop.
With explicit packaging:
* mvn clean install -Pdist
With implicit packaging:
* mvn clean install
Build time is 12 seconds slower for implicit file packaging on a Mac laptop.
The secondary use case is less frequent than the primary use case. Developer
who modifies Hadoop and their dependent project is a much smaller group. In
addition, they will probably run mvn clean install in a module rather than top
level. The amount of time saved is almost non-existed. I am in favor of
making it shorter to type for primary use case.
> mvn -Ptar and -Pbintar are broken
