[jira] [Created] (HADOOP-15412) Hadoop KMS with HDFS keystore: No FileSystem for scheme "hdfs"

JIRA jira@apache.org
Pablo San José created HADOOP-15412:
---------------------------------------

             Summary: Hadoop KMS with HDFS keystore: No FileSystem for scheme "hdfs"
                 Key: HADOOP-15412
                 URL: https://issues.apache.org/jira/browse/HADOOP-15412
             Project: Hadoop Common
          Issue Type: Bug
          Components: kms
    Affects Versions: 2.9.0, 2.7.2
         Environment: RHEL 7.3

Hadoop 2.7.2 and 2.7.9

 
            Reporter: Pablo San José


I have been trying to configure the Hadoop kms to use hdfs as the key provider but it seems that this functionality is failing. 

I followed the Hadoop docs for that matter, and I added the following field to my kms-site.xml:
{code:java}
<property>
   <name>hadoop.kms.key.provider.uri</name>
   <value>jceks://[hidden email]/kms/test.jceks</value>
   <description>
      URI of the backing KeyProvider for the KMS.
   </description>
</property>{code}
That route exists in hdfs, and I expect the kms to create the file test.jceks for its keystore. However, the kms failed to start due to this error:
{code:java}

For what I could manage to understand, it seems that this error is because there is no FileSystem implemented for HDFS. I have looked up this error but it always refers to a lack of jars for the hdfs-client when upgrading, which I have not done (it is a fresh installation). I have tested it using Hadoop 2.7.2 and 2.9.0

Thank you in advance.
