-----------------------------------------
Summary: Fix tracing documention reflecting the update to htrace-4
Key: HADOOP-12452
URL: https://issues.apache.org/jira/browse/HADOOP-12452
Project: Hadoop Common
Issue Type: Bug
Components: tracing
Reporter: Masatake Iwasaki
Assignee: Masatake Iwasaki
The sample code in Tracing.md have some problems.
* compilation error by not importing Tracer.
* generic options are not reflected because Tracer is initialized before
ToolRunner#run.
* it may be confusing to use FsShell in example because it has embedded Tracer
now.
