Affects Versions: 1.0.0, 0.20.205.0
Environment: in core-site.xml:
{code:xml}
<property>
<name>hadoop.security.authentication</name>

Reporter: Evert Lammerts
Priority: Minor
If ssl is enabled (dfs.https.enable) but ssl-server.xml is not available, a DN will crash during startup while setting up an SSL socket with a NullPointerException:

The same happens if I set an absolute path to an existing dfs.https.server.keystore.resource - in this case the file cannot be found but not even a WARN is given.
Since in dfs.https.server.keystore.resource we know we need to have 4 properties specified (ssl.server.truststore.location, ssl.server.keystore.location, ssl.server.keystore.password, and ssl.server.keystore.keypassword) we should check if they are set and throw an IOException if they are not.
