Description
We collect variety of statistics in DataNodes and expose them via JMX. Aggregating some of the high level statistics which we are already collecting in DataNodeMetrics (like bytesRead,bytesWritten etc) over a configurable time window will create a central repository accessible via JMX and UI.
Breaking this into 3 parts as suggested by arpitagarwal
- Generate usage report on DN. (will handle in this jira)
- Pass usage report to NN periodically.
- Process report on NN and expose stats via JMX.
