Description

After HADOOP-11311, key names has been restricted and uppercase key names are not allowed. This section of TransparentEncryption.md should be modified.

1. As the normal user, create a new encryption key
   hadoop key create myKey

1. As the super user, create a new empty directory and make it an encryption zone
   hadoop fs -mkdir /zone
   hdfs crypto -createZone -keyName myKey -path /zone

1. chown it to the normal user
   hadoop fs -chown myuser:myuser /zone

1. As the normal user, put a file in, read it out
   hadoop fs -put helloWorld /zone
   hadoop fs -cat /zone/helloWorld

"myKey" is not allowed here.
