[jira] [Created] (HADOOP-12561) Add documentation about metrics system

 Summary: Add documentation about metrics system
 Key: HADOOP-12561
 URL: https://issues.apache.org/jira/browse/HADOOP-12561
 Project: Hadoop Common
  Issue Type: Improvement
  Components: documentation
Reporter: Masatake Iwasaki
Assignee: Masatake Iwasaki


Though there is [reference of metric 
items|https://hadoop.apache.org/docs/r2.7.1/hadoop-project-dist/hadoop-common/Metrics.html],
 we have no documentation about metrics system and configuration. Adding 
concise documentation about metrics system would help users, admins and 
developers.

[jira] [Created] (HADOOP-12556) KafkaSink jar files are created but not copied to target dist

[Babak Behzad (JIRA)]

-

 Summary: KafkaSink jar files are created but not copied to target 
dist
 Key: HADOOP-12556
 URL: https://issues.apache.org/jira/browse/HADOOP-12556
 Project: Hadoop Common
  Issue Type: Bug
Reporter: Babak Behzad
Assignee: Babak Behzad


There is a hadoop-kafka artifact missing from hadoop-tools-dist's pom.xml which 
was causing the compiled Kafka jar files not to be copied to the target dist 
directory. The new patch adds this in order to complete this fix.
