> Cannot Delete Key with / in the key name
> ----------------------------------------
>
> Key: HADOOP-16216
> URL: https://issues.apache.org/jira/browse/HADOOP-16216
> Project: Hadoop Common
> Issue Type: Bug
> Reporter: Istvan Vajnorak
> Priority: Major
>
> Users can create keys with / in the path but eventually are unable to delete
> them due to the way the hadoop key command encodes URLs.
> Below are the steps to reproduce and the only way to get rid of such a key is
> to invoke the REST API directly.
> Please check if hadoop key command's implementation to be changed to cater
> for this, or implement a special character filtering to not allow such keys
> to be created.
> 1. Create a key with a / in it's name: [root@nightly514-1 hadoop-kms]# hadoop
> key create my/key my/key has been successfully created with options
> Options\{cipher='AES/CTR/NoPadding', bitLength=128, description='null',
> attributes=null}.
> org.apache.hadoop.crypto.key.kms.LoadBalancingKMSClientProvider@5890e879 has
> been updated.
> 2. List and ensure key is there:
> {code}
> [root@nightly514-1 hadoop-kms]# hadoop key list | grep my/key
> my/key
> {code}
> 3. Try to delete with normal hadoop key command:
> {code}
> [root@nightly514-1 hadoop-kms]# hadoop key delete my/key
> You are about to DELETE all versions of key my/key from KeyProvider
> org.apache.hadoop.crypto.key.kms.LoadBalancingKMSClientProvider@2890c451.
> Continue? (Y or N) y
