> A few properties are not documented.
> {{hadoop.security.group.mapping.ldap.ssl.keystore.password}}
> This property is used as an alias to get password from credential providers, or, fall
back to using the value as password in clear text. There is also a caveat that credential
providers can not be a HDFS-based file system, as mentioned in HADOOP-11934, to prevent cyclic
dependency issue.
> This should be documented in core-default.xml and GroupsMapping.md
> {{hadoop.security.credential.clear-text-fallback}}
> This property controls whether or not to fall back to storing credential password as
cleartext.
> This should be documented in core-default.xml.
> {{hadoop.security.credential.provider.path}}
> This is mentioned in _CredentialProvider API Guide_, but not in core-default.xml
> The "Supported Features" in _CredentialProvider API Guide_ should link back to GroupsMapping.md#LDAP
Groups Mapping 
> {{hadoop.security.credstore.java-keystore-provider.password-file}}
> This is the password file to protect credential files.
