Description

Metrics emited by Chukwa Agent through MetricsContext is structured as:

contextName: chukwaHttpSender
recordName: chukwaHttpSender

The same context is repeated twice in the naming hierarchy.

Ideally, the structure should be:

contextName: chukwaAgent
recordName: httpSender

Therefore, the metrics can be collected in chukwa table, column family: agent_httpSender. In sequence file, it will be chukwa data type directory, and hashmap looks like:

{ "contextName":"chukwaAgent","recordName":"httpSender",...}
