[jira] [Created] (HADOOP-12778) hadoop.security.key.provider.path is not documented.

Takashi Ohnishi created HADOOP-12778:
----------------------------------------

             Summary: hadoop.security.key.provider.path is not documented.
                 Key: HADOOP-12778
                 URL: https://issues.apache.org/jira/browse/HADOOP-12778
             Project: Hadoop Common
          Issue Type: Bug
          Components: kms
    Affects Versions: 2.7.2, 3.0.0
            Reporter: Takashi Ohnishi


The "Transparent Encryption in HDFS" page does not tell about this, but {{hdfs crypto}} operations failed with the below error.
{code}
There are no valid KeyProviders configured. No key
was created. You can use the -provider option to specify
a provider to use.
{code}

I have found hadoop-common-project/hadoop-common/src/main/java/org/apache/hadoop/crypto/key/KeyProviderFactory.java uses this parameter.
By setting this parameter in core-site.xml, {{hdfs crypto}} command runs successfully.
