how to remove a hdfs path from encryption zone

dsharma — Tue, 09 Aug 2016 01:22:58 GMT

I created a key and then using that key created an encryption zone on a path

hdfs dfs -mkdir /enczone
hadoop crypto -createZone -keyName testkey -path /enczone

now i have deleted that key testkey.

but if I try to access the path /enczone.

I get Null pointer exception saying no key found testkey, looks like since path is encrypted so we get this error.

any workaround on this without creating the key again?

You should not have deleted the encryption key. You cannot just disable an encryption zone. If you can still recover the key, do that, read the data and copy it in an unencrypted zone. Then simply delete the encrypted directory and then you can delete the key. Otherwise, the data is likely lost.
