In order to set up SpanReceivers for HDFS servers,
configure what SpanReceivers you'd like to use
by putting a comma separated list of the fully-qualified class name of classes implementing SpanReceiver
in `hdfs-site.xml` property: `dfs.htrace.spanreceiver.classes`.
```xml
<property>

You can omit package name prefix if you use span receiver bundled with HTrace.
```xml
<property>
<name>dfs.htrace.spanreceiver.classes</name>
<value>LocalFileSpanReceiver</value>
</property>
```
You also need to add the jar bundling SpanReceiver to the classpath of Hadoop
on each node. (LocalFileSpanReceiver in the example above is included in the
jar of htrace-core which is bundled with Hadoop.)
See core-default.xml for a description of HTrace configuration keys. In some
cases, you will also need to add the jar containing the SpanReceiver that you
are using to the classpath of Hadoop on each node. (In the example above,
LocalFileSpanReceiver is included in the htrace-core4 jar which is bundled
with Hadoop.)
