----------------------------------------
The essence of the compatibility story
{code:java}
+ useRetryableThrottlingException = rsServices.getConfiguration()
+ .getBoolean(QuotaUtil.QUOTA_RETRYABLE_THROTTING_EXCEPTION_CONF_KEY,
+ QuotaUtil.QUOTA_RETRYABLE_THROTTING_EXCEPTION_DEFAULT);
{code}
Then
{code:java}
+ // Depending on whether we are supposed to throw a retryable IO exeption
or not, choose
+ // the correct exception type to (re)throw
+ if (e instanceof ThrottlingException) {
+ if (useRetryableThrottlingException) {
+ throw new RpcThrottlingException(e.getMessage());
+ } else {
+ throw e;
+ }
+ } else if (e instanceof RpcThrottlingException) {
+ if (useRetryableThrottlingException) {
+ throw e;
+ } else {
+ throw new ThrottlingException(e.getMessage());
+ }
+ } else {
+ LOG.warn("Unexpected exception from quota check", e);
+ throw e;
+ }
{code}
