Steve Loughran created HADOOP-13028: ---------------------------------------
Summary: add counter and timer metrics for S3A operations Key: HADOOP-13028 URL: https://issues.apache.org/jira/browse/HADOOP-13028 Project: Hadoop Common Issue Type: Sub-task Components: fs/s3, metrics Affects Versions: 2.8.0 Reporter: Steve Loughran Priority: Minor against S3 (and other object stores), opening connections can be expensive, closing connections may be expensive (a sign of a regression). S3A FS and individual input streams should have counters of the # of open/close/failure+reconnect operations, timers of how long things take. This can be used downstream to measure efficiency of the code (how often connections are being made), connection reliability, etc. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
