Chen Liang commented on HDFS-12454:
-----------------------------------
Actually, my previous comment about the 9874 port thing is not quite right. The
commands in current doc about using 9864 port is actually correct. Changing to
whatever value won't affect this.
So seems the value of {{OZONE_KSM_HTTP_BIND_PORT_DEFAULT}} is not used as I
thought of, but instead, is the RPC port client uses to talk to KSM. But then
do we really need to have this ksm address setting in sample config? Because
it's value is used only internally and Ozone works without explicitly setting
this value, just like HDFS doc does not seem to include the setting of namenode
RPC port used by client? [~cheersyang]
> Ozone : the sample ozone-site.xml in OzoneGettingStarted does not work

> 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]?
