设置Hadoop KMS

我尝试设置Hadoop KMS服务器和客户端

下面是我的kms.site.xml

<property>
   <name>hadoop.kms.key.provider.uri</name>
   <value>jceks://file@/${user.home}/kms.keystore</value>
   <description>
      URI of the backing KeyProvider for the KMS.
   </description>
</property>

<property>
   <name>hadoop.security.keystore.java-keystore-provider.password-file</name>
   <value>kms.keystore.password</value>
   <description>
     If using the JavaKeyStoreProvider, the file name for the keystore password.
   </description>
</property>

我收到下面的信息，我遗漏了什么吗

There are no valid (non-transient) providers configured.
No action has been taken. Use the -provider option to specify
a provider. If you want to use a transient provider then you
MUST use the -provider argument.

<property>
    <name>dfs.encryption.key.provider.uri</name>
    <value>kms://http@mydomain:16000/kms</value>
</property>
