Summary: Correct check for error code to detect Azure Storage
Throttling and provide retries
Key: HADOOP-13831
URL: https://issues.apache.org/jira/browse/HADOOP-13831
Project: Hadoop Common
Issue Type: Bug
Reporter: Gaurav Kanade
Azure Storage throttling affects HBase operations such as archiving old WALS
and others. In such cases the storage driver needs to detect and handle the
exception. We put in this logic to do the retries however the condition to
check for the exception is not always met due to inconsistency in which the
manner the error code is passed back. Instead the retry logic should check for
http status code (503) which is more reliable and consistent check
