Arpit Agarwal updated HDFS-8561:
--------------------------------
Description:
The default policy in RetryUtils does not retry RetriableExceptions even when
{{defaultRetryPolicyEnabled}} is true.
This was discovered via an HDFS client failing to retry
{{getFileBlockLocations}} after {{checkNNStartup}} failed.
was:
{{checkNNStartup}} currently throws an {{IOException}} if services have not yet
been started.
This propagates as a RemoteException to the client which is not retriable with
the default retry policy in RetryUtils.
> The default retry policy does not handle RetriableException correctly
