Remove Hadoop_ prefix from Hadoop Metrics Processor
---------------------------------------------------
Key: CHUKWA-556
URL: https://issues.apache.org/jira/browse/CHUKWA-556
Project: Chukwa
Issue Type: Improvement
Components: Data Processors
Environment: Java 6, MacOSX 10.6
Reporter: Eric Yang
Assignee: Eric Yang
Both Chukwa and HBase uses MetricsContext to emite Hadoop metrics format.
Therefore, it is possible to reuse the same HadoopMetricsProcessor class to
process those metrics. In HadoopMetricsProcessor is currently prepending
Hadoop_ into the metrics field name. This jira is to remove this prefix. The
DataType will be base on the user input type. i.e. Hadoop, Chukwa, HBase, and
column family or field name will be set to contextName of the MetricsContext.
