我有 hadoop-2.8.3、hive-2.3.2 和 tez（试用 0.9 和 0.8.5 版本）。tez-site 基本配置：
- tez.lib.uris：/apps/tez/apache-tez-0.8.5-bin.tar.gz（上传到hdfs）
- tez.use.cluster.hadoop-libs：假
容器日志 stderr 显示：
Error: Could not find or load main class org.apache.tez.dag.app.DAGAppMaster
YARN 资源管理器跟踪显示：
Application application_1516872625165_0011 failed 2 times due to AM

因此，容器在找不到/加载 DAGAppMaster 类时失败了两次。我忘记了什么？
