@Guilherme Colla: Looks like you don't have any live datanodes. Can you check the status of datanodes and start them if they are down/haven't started?

@Sandeep Nemuri

In the host my two datanodes is ok, but in the summary the ambari doesn't recognize the datanodes are lives

@Guilherme Colla Click on each host and start the datanode service.
