---------------------------------------
Summary: S3A to support custom retry policies; maybe failfast on
unknown host
Key: HADOOP-13205
URL: https://issues.apache.org/jira/browse/HADOOP-13205
Project: Hadoop Common
Issue Type: Sub-task
Components: fs/s3
Affects Versions: 2.8.0
Reporter: Steve Loughran
Noticed today that when connections are down, S3A retries on
UnknownHostExceptions logging noisily in the process.
# it should be possible to define or customize retry policies for an FS
instance (fail fast, exponential backoff, etc)
# we may want to explicitly have a fail-fast-if-offline retry policy, catching
the common connectivity ones.
Testing will be fun here.
