Subject [jira] [Created] (HADOOP-9464) In test*Conf.xml regexp replication factor set to 1
Date Sun, 07 Apr 2013 02:51:15 GMT
Anatoli Fomenko created HADOOP-9464:
---------------------------------------

             Summary: In test*Conf.xml regexp replication factor set to 1
                 Key: HADOOP-9464
                 URL: https://issues.apache.org/jira/browse/HADOOP-9464
             Project: Hadoop Common
          Issue Type: Bug
          Components: test
    Affects Versions: 2.0.4-alpha
            Reporter: Anatoli Fomenko
            Priority: Critical
             Fix For: 2.0.4-alpha


In some Hadoop smoke tests (testHDFSConf.xml), in expected output for RegexpComparator, a
replication factor is hard coded to 1,
 
{noformat}
    <test> <!-- TESTED -->
      <description>ls: file using absolute path</description>
      <test-commands>
        <command>-fs NAMENODE -touchz /file1</command>
        <command>-fs NAMENODE -ls /file1</command>
      </test-commands>
      <cleanup-commands>
        <command>-fs NAMENODE -rm /file1</command>
      </cleanup-commands>
      <comparators>
        <comparator>
          <type>TokenComparator</type>
          <expected-output>Found 1 items</expected-output>
        </comparator>
        <comparator>
          <type>RegexpComparator</type>
          <expected-output>^-rw-r--r--( )*1( )*[a-z]*( )*supergroup( )*0( )*[0-9]{4,}-[0-9]{2,}-[0-9]{2,}
[0-9]{2,}:[0-9]{2,}( )*/file1</expected-output>
        </comparator>
      </comparators>
    </test>
{noformat}

such as the first "1" in 

{noformat}
<expected-output>^-rw-r--r--( )*1( )*[a-z]*( )*supergroup( )*0( )*[0-9]{4,}-[0-9]{2,}-[0-9]{2,}
[0-9]{2,}:[0-9]{2,}( )*/file1</expected-output>
{noformat}.

We found in Bigtop testing on a standalone cluster that such tests fail with a default replication
factor. 

Please update the regexp in test*Conf.xml files to add a flexibility for a replication factor
that would allow to execute these tests with a variety of clusters, or inside the Bigtop.
