[jira] [Created] (HADOOP-18351) Error logging during reads

Ahmar Suhail created HADOOP-18351:
-------------------------------------

             Summary: Error logging during reads
                 Key: HADOOP-18351
                 URL: https://issues.apache.org/jira/browse/HADOOP-18351
             Project: Hadoop Common
          Issue Type: Sub-task
            Reporter: Ahmar Suhail


Look at how errors during read are logged, current implementation could flood logs with stack traces on failures.

proposed
 * errors in prefetch only logged at info with error text but not stack
 * full stack logged at debug

but: we do want the most recent failure to be raised on the next read() on the stream when there is no data in the cache.
