Subject [jira] Created: (HADOOP-340) Using wildcards in config pathnames
Date Sun, 02 Jul 2006 09:40:29 GMT
Using wildcards in config pathnames
-----------------------------------

         Key: HADOOP-340
         URL: http://issues.apache.org/jira/browse/HADOOP-340
     Project: Hadoop
        Type: Improvement

  Components: conf  
    Versions: 0.4.0    
 Environment: a cluster with different disk setups
    Reporter: Johan Oskarson
    Priority: Minor


In our cluster there's machines with very different disk setups
I've solved this by not rsyncing hadoop-site.xml, but as you probably understand this means
new settings will not get copied properly.

I'd like to be able to use wildcards in the dfs.data.dir path for example:
<property>
  <name>dfs.data.dir</name>
    <value>/home/hadoop/disk*/dfs/data</value>
</property>

then every disk mounted in that directory would be used
