-------------------------------------

             Summary: testing_azure.md documentation is misleading
                 Key: HADOOP-16710
                 URL: https://issues.apache.org/jira/browse/HADOOP-16710
             Project: Hadoop Common
          Issue Type: Bug
          Components: fs/azure
    Affects Versions: 3.2.0
            Reporter: Andras Bokor
            Assignee: Andras Bokor


testing_azure.md states that "-Dparallel-tests" will run all the integration 
tests in parallel.

But in fact using -Dparallel-tests without any value actually skips the 
integration tests and runs only the unit tests.

The reason is that to activate a profile which is able to run ITs in parallel 
requires parallel-tests property to have a value (abfs, wasb or 'both'). 
sequential-tests profile defines !parallel-tests as value which means that the 
property should not even be mentioned.

Please check the output of help:active-profiles command:

 
{code:java}
cd hadoop-tools/hadoop-azure
andrasbokor$ mvn help:active-profiles -Dparallel-tests=abfs 
- parallel-tests-abfs (source: org.apache.hadoop:hadoop-azure:3.3.0-SNAPSHOT) 
- os.mac (source: org.apache.hadoop:hadoop-project:3.3.0-SNAPSHOT) 
- hbase1 (source: org.apache.hadoop:hadoop-project:3.3.0-SNAPSHOT) {code}
{code:java}
andrasbokor$ mvn help:active-profiles -Dparallel-tests
- os.mac (source: org.apache.hadoop:hadoop-project:3.3.0-SNAPSHOT)
- hbase1 (source: org.apache.hadoop:hadoop-project:3.3.0-SNAPSHOT)
{code}
{code:java}
mvn help:active-profiles
- sequential-tests (source: org.apache.hadoop:hadoop-azure:3.3.0-SNAPSHOT)
- os.mac (source: org.apache.hadoop:hadoop-project:3.3.0-SNAPSHOT)
- hbase1 (source: org.apache.hadoop:hadoop-project:3.3.0-SNAPSHOT){code}
The help:active-profiles shows that -Dparallel-tests does not add any IT 
related profiles and results in skipping all the integration tests during 
verify phrase.
