又报错

{“error”:{“root_cause”:[{“type”:“exception”,“reason”:“failed to create blob container”}],“type”:“exception”,“reason”:“failed to create blob container”,“caused_by”:{“type”:“access_denied_exception”,“reason”:"/home/es/elasticsearch-5.1.1/data/bak/tests-hPPRVvLZQlKFEpgeauoTtA"}},“status”:500}

上述问题，大多数是因为没有切换到es的用户执行相关命令造成的。
