Subject [jira] [Created] (DL-64) DL reader should handle and retry errors infinitely
Date Wed, 02 Nov 2016 09:33:59 GMT
Khurrum Nasim created DL-64:

             Summary: DL reader should handle and retry errors infinitely
                 Key: DL-64
                 URL: https://issues.apache.org/jira/browse/DL-64
             Project: DistributedLog
          Issue Type: Improvement
            Reporter: Khurrum Nasim
            Assignee: Khurrum Nasim

The DL reader right now handles and retries most of exceptions, but still throws exceptions
when it can't handle. It is good for applications that requirements explicit controls on handling
exceptions. However it is a bit annoying for most of customers, as everyone would end up writing
the logic to catch exception and re-create readers. 

It would be nice that DL can provide some infinitely (with backoff policy) retryable reader
that automatically catch the exceptions and re-create a new reader. It would simply the logic
for writing source/spouts for stream computing jobs.
