HDFS Encryption using Java

Hi

I want to invoke below command using java .

hadoop key create myKey
hdfs crypto -createZone -keyName myKey -path /zone

Can someone point to java api documentation for this or any example to
implement this in java?

Thanks in advance.

Hi Shashi -

For the Key Provider API, I would personally use the code in KeyShell.java [1] and the tests in TestKeyProviderFactory.java [2] as examples for creating the key.

Unfortunately, I don’t have pointers for the createZone step for you but hope that is helpful.
