---------------------------------------
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://[email protected]/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.
