Hi, I'm trying to implement authentication for an ignite cluster. I've read
the blog post mentioned in other posts here but it's incomplete and also
quite old so I was hoping for some guidance. (blog post:
http://smartkey.co.uk/development/securing-an-apache-ignite-cluster/)
The authentication mechanism I'm intending to use is to check for a common
password shared by nodes. So when a node starts up by itself, it obtains
the shared password from the local system using a library call. So I need
to do two things.
* when a node starts up it needs to fetch the local password and store it
in it's own configuration
* when a node joins the cluster other nodes need to compare the provided
password with the one they have locally
So I tried setting the credentials locally as follows:
TcpDiscoverySpi spi = new TcpDiscoverySpi();
SecurityCredentials securityCredentials = new
SecurityCredentials(getModuleName(), passwordService.getPassword());
Map<String, Object> nodeAttributes = new HashMap<>();
nodeAttributes.put("org.apache.ignite.security.cred",
securityCredentials);
IgniteProductVersion igniteProductVersion = new
IgniteProductVersion();
spi.setNodeAttributes(nodeAttributes, igniteProductVersion);
However I run into an issue here because when setNodeAttributes is called on
TcpDiscoverySpi I get a NullPointerException. The exception is thrown in
line 963 which is shown below.
959 @Override public void setNodeAttributes(Map<String, Object> attrs,
IgniteProductVersion ver) {
960 assert locNodeAttrs == null;
961 assert locNodeVer == null;
962
963 if (log.isDebugEnabled()) {
964 log.debug("Node attributes to set: " + attrs);
965 log.debug("Node version to set: " + ver);
966 }
967
968 locNodeAttrs = attrs;
969 locNodeVer = ver;
970 }
The instance of IgniteLogger named 'log' is null when this method is called.
This seems like a bug to me but if it's not, am I doing something wrong? Is
there another way I should be fetching and setting this property on my local
node?
