[jira] Created: (HADOOP-1267) change default config to be single node rather than "local" for both map/reduce and hdfs

change default config to be single node rather than "local" for both map/reduce and hdfs
----------------------------------------------------------------------------------------

                 Key: HADOOP-1267
                 URL: https://issues.apache.org/jira/browse/HADOOP-1267
             Project: Hadoop
          Issue Type: Task
          Components: conf
            Reporter: Owen O'Malley
         Assigned To: Owen O'Malley
             Fix For: 0.13.0


I propose that we change the default config to be set up for a single node rather than the current "local", which uses direct file access and the local job runner.

[jira] Commented: (HADOOP-1267) change default config to be single node rather than "local" for both map/reduce and hdfs

Doug Cutting commented on HADOOP-1267:
--------------------------------------

Why?  Right now, things work out of the box w/o starting daemons, worrying about firewalls, etc.  For applications like Nutch, many (most?) users never bother running a cluster, but they get the comfort that their code is future-proofed for scalability.

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

>From Doug: We could include a confg/pseudo-cluster.xml file, that folks could use with 'bin/hadoop -conf conf/pseudo-cluster.xml ...'.

>From Nige: I suggest something like hadoop-site-localhost.xml or localhost-cluster.xml.  It would define, at a minimum, these properties:

  <property>
    <name>fs.default.name</name>
    <value>localhost:9000</value>
  </property>

  <property>
    <name>mapred.job.tracker</name>
    <value>localhost:9001</value>
  </property>

  <property>
    <name>dfs.replication</name>
    <value>1</value>
  </property>
