> 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: 2.7.2, 2.9.0
> Environment: RHEL 7.3
> Hadoop 2.7.2 and 2.7.9
>
> Reporter: Pablo San José
> Priority: Major
>
> 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://h...@nn1.example.com/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}
> ERROR: Hadoop KMS could not be started REASON:

> 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.
