Lookup Hbase Tbl from UDF (Beeline , Hbase,Delegation Tokens) - hive

Question

I have a requirement to write Custom UDF for data lookup from Hbase Table .
NOTE : I have done Unit Testing with HIVE . It seems to be working .
But when I use the same UDF Beeline, Its failed . By default Cloudera restricts impersonation and allows only hive user for running queries in Beeline. On Job startup , YarnChild is setting the following delegations tokens.
I want to add token (Kind : HBASE_AUTH_TOKEN ) for dealing with Hbase.
Kind: mapreduce.job
Kind: HDFS_DELEGATION_TOKEN
Kind: kms-dt
I researched and found out how HbaseStorageHandler is using Delegation Token ( i.e HBASE_AUTH_TOKEN ) for Hbase . So I used the same set of functions and its not working either .
Functions from HbasestorageHandler (to obtain tokens to Job ) :
private void addHBaseDelegationToken(Configuration conf, JobConf jconf) throws IOException {
if (User.isHBaseSecurityEnabled(conf)) {
try {
logger.info("isHbaseSecurityEnabled :True ");
User e = User.getCurrent();
logger.info("isHbaseSecurityEnabled :User ==> " + e.toString());
Token authToken = getAuthToken(conf, e);
logger.info("isHbaseSecurityEnabled :AuthToken==> "+authToken.toString());
Job job = new Job(conf);
if(authToken == null) {
UserGroupInformation ugi = UserGroupInformation.getLoginUser();
ugi.setAuthenticationMethod(UserGroupInformation.AuthenticationMethod.KERBEROS);
e.obtainAuthTokenForJob(jconf);
} else {
logger.info("authToken is not null"+authToken.toString());
job.getCredentials().addToken(authToken.getService(), authToken);
}
logger.info("obtained Token /....");
} catch (InterruptedException var5) {
throw new IOException("Error while obtaining hbase delegation token", var5);
}
}
}
private static Token<AuthenticationTokenIdentifier> getAuthToken(Configuration conf, User user) throws IOException, InterruptedException {
ZooKeeperWatcher zkw = new ZooKeeperWatcher(conf, "mr-init-credentials", (Abortable) null);
Token var4;
try {
String e = ZKClusterId.readClusterIdZNode(zkw);
logger.info("====== clusterID : " + e);
var4 = (new AuthenticationTokenSelector()).selectToken(new Text(e), user.getUGI().getTokens());
if (var4 == null) {
logger.info("var4 is null===========================");
} else {
logger.info("====== Hbase Token : " + var4.toString());
}
} catch (KeeperException var8) {
throw new IOException(var8);
} catch (NullPointerException np) {
return null;
} finally {
zkw.close();
}
return var4;
}
After calling addHBaseDelegationToken() in configure() of UDF. I am getting the following exception .I am not sure How I can make hvie user to talk with Hbase as hive.keytab is handled by Cloudera and its secured.
Any Inputs might be helpful. Thanks !
