Hi Andy. With DEBUG enabled, what seems to be slow is that: [DEBUG] Adding artifact: org.apache.commons:commons-math:jar:2.1 with file: /home/jmspaggi/.m2/repository/org/apache/commons/commons-math/2.1/commons-math-2.1.jar to assembly location: lib/commons-math-2.1.jar. [DEBUG] Adding file: /home/jmspaggi/.m2/repository/org/apache/commons/commons-math/2.1/commons-math-2.1.jar to archive location: hbase-0.94.6-SNAPSHOT/lib/commons-math-2.1.jar [DEBUG] Adding artifact: commons-net:commons-net:jar:1.4.1 with file: /home/jmspaggi/.m2/repository/commons-net/commons-net/1.4.1/commons-net-1.4.1.jar to assembly location: lib/commons-net-1.4.1.jar. [DEBUG] Adding file: /home/jmspaggi/.m2/repository/commons-net/commons-net/1.4.1/commons-net-1.4.1.jar to archive location: hbase-0.94.6-SNAPSHOT/lib/commons-net-1.4.1.jar About 3 minutes, displaying one line every 1 to 2 seconds.
Then this is taking a lot of time: [INFO] Copying files to /tmp/hbase-0.94/target/hbase-0.94.6-SNAPSHOT It's now running for 10 minutes and seems it's doing nothing. This is what I saw without the debug enabled. I'm building on an SSD drive. It's only about 250MB. I can even build it in memory if required. But I don't think it's because of the disk.
