Example 6 with GrantDesc

use of org.apache.hadoop.hive.ql.plan.GrantDesc in project hive by apache.

the class HiveAuthorizationTaskFactoryImpl method createGrantTask.

@Override

    List<PrivilegeDesc> privilegeDesc = analyzePrivilegeListDef((ASTNode) ast.getChild(0));

    boolean grantOption = false;
    PrivilegeObjectDesc privilegeObj = null;
    if (ast.getChildCount() > 2) {
        for (int i = 2; i < ast.getChildCount(); i++) {

    String userName = SessionState.getUserFromAuthenticator();
    GrantDesc grantDesc = new GrantDesc(privilegeObj, privilegeDesc, principalDesc, userName, PrincipalType.USER, grantOption);
    return TaskFactory.get(new DDLWork(inputs, outputs, grantDesc), conf);
