LiXin Ge commented on HDFS-13087:
---------------------------------

Thanks [~xiaochen] for reviewing this again.
{quote}I think we should go with the default Enum#equals comparison
{quote}
Yes, I'm done, use {{EqualsBuilder}} Instead of the new added {{isEqual}} now.
{quote}We can use HashCodeBuilder and EqualsBuilder to implement the EZI equals 
method.
{quote}
Done in the new attached patch.
{quote}EZI#getEncryptionZoneForPath: can we still use the existing logic to get 
from encryptionZones?
{quote}
Good idea, done.
{quote}In the new method, parameter name typo 'sanpshotId'.
{quote}
Done, sorry for the typo, and thanks for your carefully review.
