Dear Wiki user, You have subscribed to a wiki page or wiki category on "Hadoop Wiki" for change notification.
The "Ozone" page has been changed by ArpitAgarwal: https://wiki.apache.org/hadoop/Ozone?action=diff&rev1=4&rev2=5 - <<TableOfContents(2)>> + The ''Ozone Quick Start Guide'' has moved to the [[https://cwiki.apache.org/confluence/display/HADOOP/Ozone|Apache Confluence wiki]]. - = Introduction = - Ozone is an Object Store for Hadoop that is currently under development. See the Ozone Apache Jira [[https://issues.apache.org/jira/browse/HDFS-7240|HDFS-7240]] for more details. Ozone is currently in a prototype phase. - - This wiki page is intended as a guide for Ozone contributors. - - = Compiling Ozone = - Setup your development environment if you haven't done so already ([[https://wiki.apache.org/hadoop/HowToContribute|Instructions here]]). Switch to the HDFS-7240 branch, apply the in-progress patch for [[https://issues.apache.org/jira/browse/HDFS-10363|HDFS-10363]] and build a Hadoop distribution as usual. - - = Configuration = - Create a new ozone-site.xml file in your Hadoop configuration directory and add the following settings for a bare minimal configuration. - - {{{ - <configuration> - <property> - <name>ozone.enabled</name> - <value>true</value> - </property> - - <property> - <name>ozone.handler.type</name> - <value>local</value> - </property> - - <property> - <name>ozone.scm.client.address</name> - <value>127.0.0.1:9860</value> - </property> - </configuration> - }}} - - The default client port is 9860 and the default service port is 9861. These ports are used by clients and DataNodes respectively to connect to the StorageContainerManager service. - - These port numbers can be changed with the `ozone.scm.client.address` and `ozone.scm.datanode.address` settings respectively. - - = Starting Services = - Format the HDFS NameNode and start the NameNode and DataNode services as usual. Then stop the NameNode and start the Ozone StorageContainerManager using the shell command - {{{ - $ hdfs --daemon start scm - }}} - - The requirement to first start then stop the NameNode will be fixed soon. - - = Performing Ozone REST operations = - [[https://issues.apache.org/jira/secure/attachment/12799549/ozone_user_v0.pdf|Ozone REST API specification]] - --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected]
