Subject [Hadoop Wiki] Update of "Hbase/HowToContribute" by JeffHammerbacher
Date Sun, 06 Jun 2010 03:07:20 GMT
Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Hadoop Wiki" for change notification.

The "Hbase/HowToContribute" page has been changed by JeffHammerbacher.
http://wiki.apache.org/hadoop/Hbase/HowToContribute?action=diff&rev1=16&rev2=17

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

    * By default, do not let tests write any temporary files to {{{/tmp}}}.  Instead, the
tests should write to the location specified by the {{{test.build.data}}} system property.
The {{{org.apache.hadoop.hbase.HBaseTestingUtility}}} class has some utility methods to assist
with this.
    * If a HBase cluster is needed by your test, you should use the {{{org.apache.hadoop.hbase.HBaseTestingUtility}}}
to start and stop the cluster. See the {{{org.apache.hadoop.hbase.client.TestAdmin}}} and
{{{org.apache.hadoop.hbase.client.TestFromClientSide}}} classes as these are good examples
of how the testing utilities can be used.
    * Place your class in the {{{src/test}}} tree.
-   * you can run all the unit test with the command {{{mvn test}}}, or you can run a specific
unit test with the command {{{mvn test -Dtest=<ClassName>}}} (For example {{{mvn test
-Dtest=TestHBaseCluster}}})
+   * You can run all the unit tests with the command {{{mvn test}}}, or you can run a specific
unit test with the command {{{mvn test -Dtest=<ClassName>}}} (For example {{{mvn test
-Dtest=TestHBaseCluster}}})
-   * if you want to quickly build the code without running the tests you can run the command
{{{mvn install -DskipTests}}}
+   * If you want to quickly build the code without running the tests you can run the command
{{{mvn install -DskipTests}}}
+   * If your test requires a port, be sure to use an ephemeral port by requesting port 0
in your code and passing the assigned port to the client.
  
  === New to Hbase ===
  For those contributors that are new to HBase, there is a label that is added to jira items
that are appropriate for you. When finding issues, add a search criteria for the label "noob"
to find all of these tasks. Furthermore, all contributors when logging jira items should consider
whether the new issue could be assigned to a HBase noob and add the label appropriately.
