Masatake Iwasaki updated HADOOP-11544:
--------------------------------------
Attachment: HADOOP-11544.002.patch
Thanks for the comment [~ajisakaa]. I removed the entry of
"hadoop.htrace.sampler" from core-default.xml because the default
(NeverSampler) is defined in org.apache.htrace.SamplerBuilder.
I would like to left the description in Tracing.apt.vm because users still can
use "hadoop.htrace.sampler" for setting trace sampler though the config key
should be specified as {{TraceUtils.HTRACE_CONF_PREFIX +
SamplerBuilder.SAMPLER_CONF_KEY}} rather than
{{CommonConfigurationKeys.HADOOP_TRACE_SAMPLER}} in java code.
> Remove unused configuration keys for tracing
