------------------------------------
Summary: Load the included Credential classes by default
Key: OOZIE-1656
URL: https://issues.apache.org/jira/browse/OOZIE-1656
Project: Oozie
Issue Type: Improvement
Components: core
Affects Versions: 3.3.2
Reporter: Robert Kanter
Currently, to use the {{<credentials>}} section, the user has to add the
associated Credentials class to a property in oozie-site.xml and also come up
with a name for that class.
To make things easier for the user, and to standardize the names, I think it
would be helpful to include the built-in Credentials classes by default. We
can do it similar to how we do the Services and some other properties where we
have a {{.ext}} version of the property. i.e.
{code:title=oozie-default.xml}
<property>
<name>oozie.credentials.credentialclasses</name>
<value>
hcat=org.apache.oozie.action.hadoop.HCatCredentials,
hbase=org.apache.oozie.action.hadoop.HbaseCredentials,
</value>
<description>
foo
</description>
</property>
{code}
{code:title=oozie-site.xml}
<property>
<name>oozie.credentials.ext.credentialclasses</name>
<value> </value>
<description>
bar
</description>
</property>
{code}
Oozie would then load the built-in ones by default (and with standardized
names) and users could add/override custom ones.
The documentation should also be updated.
