---------------------------------------
Summary: log DNS addresses on s3a init
Key: HADOOP-13873
URL: https://issues.apache.org/jira/browse/HADOOP-13873
Project: Hadoop Common
Issue Type: Sub-task
Components: fs/s3
Reporter: Steve Loughran
Priority: Minor
HADOOP-13871 has shown that network problems can kill perf, and that it's v.
hard to track down, even if you turn up the logging in hadoop.fs.s3a and
com.amazon layers to debug.
we could maybe improve things by printing out the IPAddress of the s3 endpoint,
as that could help with the network tracing. Printing from within hadoop shows
the one given to S3a, not a different one returned by any load balancer.
