Yi Liu commented on HDFS-7209:
------------------------------

The jenkins says "java.lang.NoSuchMethodError: 
org.apache.hadoop.crypto.key.kms.KMSClientProvider.getEncKeyQueueSize", but 
actually it exists, re-upload the patch to re-trigger Jenkins.

> fill the key queue when creating encryption zone

> Currently when creating file in an encryption zone for the first time, key 
> provider will get bunch of keys from KMS and fill in the queue. It will take 
> some time. We can initialize the key queue when creating the encryption zone 
> by admin.
