Chen Liang updated HDFS-12454:
------------------------------
Attachment: HDFS-12454-HDFS-7240.002.patch
Thanks [~cheersyang] for the follow up!
Thanks for the illustration about the ports, I did realize I misunderstood
where they got used earlier, and after check with Anu, I have filed HDFS-12475
to add this to doc somewhere to avoid further confusion.
And it's an excellent catch on the fact that the default config will not work
for multi-node setup so the config keys should be made explicit for users to
note and change.
Post v002 patch where:
1. all the {{ozone.container.metadata.dirs}} references have been changed to
{{ozone.metadata.dirs}}
2. {{ozone.scm.datanode.id}} is generated under the metadata dir by default, so
can be omitted from config.
3. Added ksm address back, and in addition to ksm address, I also included scm
addresses, right now scm uses three addresses, each as one separate config
entry. I think they should be merged to just one entry such as "scm.address".
will follow up with another JIRA.

> In OzoneGettingStarted.md there is a sample ozone-site.xml file. But there
> are a few issues with it.
> 1.
> {code}
> <property>
> <name>ozone.scm.block.client.address</name>
> <value>scm.hadoop.apache.org</value>
> </property>
> <property>
> <name>ozone.ksm.address</name>
> <value>ksm.hadoop.apache.org</value>
> </property>
> {code}
> The value should be an address instead.
> 2.
> {{datanode.ObjectStoreHandler.<init>(ObjectStoreHandler.java:103)}} requires
> {{ozone.scm.client.address}} to be set, which is missing from this sample
> file. Missing this config will seem to cause failure on starting datanode.
> 3.
> {code}
> <property>
> <name>ozone.scm.names</name>
> <value>scm.hadoop.apache.org</value>
> </property>
> {code}
> This value did not make much sense to, I found the comment in
> {{ScmConfigKeys}} that says
> {code}
> // ozone.scm.names key is a set of DNS | DNS:PORT | IP Address | IP:PORT.
> // Written as a comma separated string. e.g. scm1, scm2:8020, 7.7.7.7:7777
> {code}
> So maybe we should write something like scm1 as value here.
> 4. I'm not entirely sure about this, but
> [here|https://wiki.apache.org/hadoop/Ozone#Configuration] it says
> {code}
> <property>
> <name>ozone.handler.type</name>
> <value>local</value>
> </property>
> {code}
> is also part of minimum setting, do we need to add this [~anu]?
