Subject [Hadoop Wiki] Update of "Ozone" by ArpitAgarwal
Date Tue, 17 Oct 2017 17:02:44 GMT
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]]
