-------------------------------------
Summary: Log metrics for slow I/Os
Key: IMPALA-9033
URL: https://issues.apache.org/jira/browse/IMPALA-9033
Project: IMPALA
Issue Type: Improvement
Components: Backend
Reporter: Tim Armstrong
Assignee: Tim Armstrong
We should detect I/Os that take longer than a configurable threshold, e.g 10
seconds might be reasonable and then log some extra information about them -
any of the metrics we get from the HDFS client.
This will help debug certain perf issues and hangs.
