[jira] [Created] (HDFS-4698) provide client-side metrics for remote
reads, local reads, and short-circuit reads
Colin Patrick McCabe created HDFS-4698:
------------------------------------------
Summary: provide client-side metrics for remote reads, local reads, and short-circuit reads
Key: HDFS-4698
URL: https://issues.apache.org/jira/browse/HDFS-4698
Project: Hadoop HDFS
Issue Type: Improvement
Components: hdfs-client
Affects Versions: 2.0.3-alpha
Reporter: Colin Patrick McCabe
Assignee: Colin Patrick McCabe
Priority: Minor
We should provide metrics to let clients know how many bytes of data they have read remotely, versus locally or via short-circuit local reads. This will allow clients to know how well they're doing at bringing the computation to the data, which will be useful in evaluating placement policies and cluster configurations.
