Subject [jira] [Commented] (HADOOP-7583) mvn -Ptar and -Pbintar are broken
Date Thu, 25 Aug 2011 20:10:33 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-7583?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13091268#comment-13091268

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.
