Add ability to stream Hadoop metrics through syslog appender
-------------------------------------------------------------
Key: CHUKWA-545
URL: https://issues.apache.org/jira/browse/CHUKWA-545
Project: Chukwa
Issue Type: New Feature
Components: data collection
Reporter: Eric Yang
Assignee: Eric Yang
Fix For: 0.5.0
Hadoop metrics is currently streaming through Chukwa's customized log4j
appender to delegate the registration of metrics file with Chukwa agent. Both
Chukwa agent and chukwa hadoop client keeps track of list of registered
adaptors. It is error prone to have adaptor list tracked in two different
places. In addition, the management of metrics files is also a problem.
Hence, I propose to remove both limitation by using syslog appeender to send
hadoop metrics to Chukwa. This approach eliminates the adaptor and file
management problems.
