why are tests disabled with -DskipTests during package build ?
Good day -
I'm a newbie Hadoop user - I'm trying to build from the latest hadoop-2.2.0-src.tar.gz tarball,
and the BUILDING.txt says:
"
* Use -DskipTests to skip tests when running the following Maven goals:
'package', 'install', 'deploy' or 'verify'
"
Why is this ? Is it because tests will fail ? It would appear so - without the -DskipTests option,
the maven build command I'm using:
$ mvn package -Pdist,native,docs,src -DskipTests -Dtar
fails with :
"
Results :
Failed tests: testSocketIOWithTimeout(org.apache.hadoop.net.TestSocketIOWithTimeout)
Tests run: 2015, Failures: 1, Errors: 0, Skipped: 15
"
Why is it not an issue that this test fails ?
How can I ensure the test passes when the resulting package is installed ?
I try running the command line in the log after the build with -DskipTests succeed:
Forking command line: /bin/sh -c cd /home/jason/work/3P/hadoop-2.2.0/src/hadoop-common-project/hadoop-common && /opt/jdk1.7.0_45/jre/bin/java -Xmx1024m -XX:+HeapDumpOnOutOfMemoryError -jar /home/jason/work/3P/hadoop-2.2.0/src/hadoop-common-project/hadoop-common/target/surefire/surefirebooter6164738766838875687.jar /home/jason/work/3P/hadoop-2.2.0/src/hadoop-common-project/hadoop-common/target/surefire/surefire1646141947230873924tmp /home/jason/work/3P/hadoop-2.2.0/src/hadoop-common-project/hadoop-common/target/surefire/surefire_1465676543897623396354tmp

And I get output ending in :

$ echo $?
0
Does this mean the test passed or failed ?
This is when building on an x86_64 Linux CentOS 6.4 platform, with Oracle Java JDK 1.7.0_45 + 64-bit JRE -
I'm re-building because I need the 64-bit native libraries which seem not to be built or distributed by Apache.
I'm very dubious about using the resulting package without it having passed its test suite .
Any ideas how to run the test suite outside the build process after installation ?
Or how to run the individual TestSocketIOWithTimeout test and obtain some indication of its success or failure ?
Any help / ideas would be much appreciated.
Thanks & Regards,
Jason
