> TestAclsEndToEnd is failing consistently in HADOOP-14521.
> The reason behind it is LoadBalancingKMSClientProvider#warmUpEncryptedKeys
> swallows IOException while KMSClientProvider#warmUpEncryptedKeys throws all
> the way back to createEncryptionZone and creation of EZ fails.
> Following are the relevant piece of code snippets.
> {code:title=KMSClientProvider.java|borderStyle=solid}
> @Override
> public void warmUpEncryptedKeys(String... keyNames)
> throws IOException {
> try {
> encKeyVersionQueue.initializeQueuesForKeys(keyNames);
> } catch (ExecutionException e) {
> throw new IOException(e);
> }
> }
> {code}
> {code:title=LoadBalancingKMSClientProvider.java|borderStyle=solid}
> // This request is sent to all providers in the load-balancing group
> @Override
> public void warmUpEncryptedKeys(String... keyNames) throws IOException {
> for (KMSClientProvider provider : providers) {
> try {
> provider.warmUpEncryptedKeys(keyNames);
> } catch (IOException ioe) {
> LOG.error(
> "Error warming up keys for provider with url"
> + "[" + provider.getKMSUrl() + "]", ioe);
> }
> }
> }
> {code}
> In HADOOP-14521, I intend to always instantiate
> LoadBalancingKMSClientProvider even if there is only one provider so that the
> retries can applied at only one place.
> We need to decide whether we want to fail in both the case or continue.
