Subject [jira] Commented: (HADOOP-6383) Add simulated data node cluster start/stop commands in hadoop-dameon.sh .
Date Fri, 20 Nov 2009 22:11:39 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-6383?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12780785#action_12780785

Konstantin Boudnik commented on HADOOP-6383:

I believe the simulated cluster is intended for testing. {{bin/}} has scripts for a production
cluster. Thus, I'd suggest to move these new wrapper scripts to {{src/test/bin}} instead.
Keep in mind that the aforementioned directory is shared with all subprojects.

> Currently there are no commands supported for starting or stopping simulated data node
> To start simulated data node cluster we need to export extra class paths required for
> {noformat}
> bin/hadoop-daemon.sh start org.apache.hadoop.hdfs.DataNodeCluster  -simulated -n $DATANODE_PER_HOST
> {noformat}
> {noformat}
> bin/hadoop-daemon.sh stop org.apache.hadoop.hdfs.DataNodeCluster  -simulated  
> {noformat}
> For better user interface we should add DataNodeCluster start stop option in hadoop-daemon.sh
