Examples with BlockingInterface org.apache.hadoop.hbase.protobuf.generated.AccessControlProtos.AccessControlService.BlockingInterface used on opensource projects

Example 1 with BlockingInterface

use of org.apache.hadoop.hbase.protobuf.generated.AccessControlProtos.AccessControlService.BlockingInterface in project hbase by apache.

the class AccessControlClient method getAccessControlServiceStub.

private static BlockingInterface getAccessControlServiceStub(Table ht) throws IOException {
    CoprocessorRpcChannel service = ht.coprocessorService(HConstants.EMPTY_START_ROW);
    BlockingInterface protocol = AccessControlProtos.AccessControlService.newBlockingStub(service);
    return protocol;
}

Example 2 with BlockingInterface

use of org.apache.hadoop.hbase.protobuf.generated.AccessControlProtos.AccessControlService.BlockingInterface in project hbase by apache.

the class AccessControlClient method getUserPermissions.

/**
   * List all the userPermissions matching the given pattern. If pattern is null, the behavior is
   * dependent on whether user has global admin privileges or not. If yes, the global permissions
   * along with the list of superusers would be returned. Else, no rows get returned.
   * @param connection The Connection instance to use
   * @param tableRegex The regular expression string to match against
   * @return - returns an array of UserPermissions
   * @throws Throwable
