Masatake Iwasaki commented on HDFS-9080:
----------------------------------------
* hdfs-default.xml: This should be {{fs.client.htrace.sampler.classes}}. This
also should be moved to core-default.xml? FS_CLIENT_HTRACE_PREFIX is defined in
CommonConfigurationKeys.java of hadoop-common.
{code}
- <name>dfs.htrace.spanreceiver.classes</name>
+ <name>dfs.client.htrace.sampler.classes</name>
{code}
* TestHdfsConfigFields.java: We don't need this if the default configuration
above is moved to core-default.xml.
{code}
- // Ignore SpanReceiveHost properties
- xmlPropsToSkipCompare.add("dfs.htrace.spanreceiver.classes");
- xmlPropsToSkipCompare.add("dfs.client.htrace.spanreceiver.classes");
+ // Ignore HTrace properties
+ xmlPropsToSkipCompare.add("fs.client.htrace");
+ xmlPropsToSkipCompare.add("hadoop.htrace");
{code}
* {{dfs.htrace.spanreceiver.classes}} is sometimes found in Tracing.md. It
should be fixed as {{hadoop.htrace.span.receiver.classes}}.
> update htrace version to 4.0
