当使用tez.lib.uris==tez.tar.gz时，TEZ不起作用

Question

我通过Ambari 2.6.1安装了Tez 0.9.1。成功地将tez.tar.gz复制到hdfs。但是当服务检查时-我得到了错误。深入研究yarn logs -applicationId APP_ID的日志，我发现了Error: Could not find or load main class org.apache.tez.dag.app.DAGAppMaster。虽然DAG jar是在tar.gz中。tez.lib.uris==${fs.default.name}/hdp/apps/${hdp.version}/tez/tez.tar.gz.如果我将其解压到hdfs中，然后更改为：tez.lib.uris==${fs.default.name}/hdp/apps/${hdp.version}/tez,${fs.default.name}/hdp/apps/${hdp.version}/tez/lib一切正常，服务检查正常。尝试:手动复制tar.gz，将chmod777设置为它，各种tez.lib.uris.classpath值-都不起作用。

感谢您的帮助！提前感谢

找到了解决方案。需要在yarn-site.xml中使用：/usr/hdp/current/tez-client/*,/usr/hdp/current/tez-client/lib/*扩展yarn.application.classpath，在我的例子中，最终的值是：

{{hadoop_home}}/conf,{{hadoop_home}}/*,{{hadoop_home}}/lib/*,/usr/hdp/current/hadoop-hdfs-client/*,/usr/hdp/current/hadoop-hdfs-client/lib/*,/usr/hdp/current/hadoop-yarn-client/*,/usr/hdp/current/hadoop-yarn-client/lib/*,/usr/hdp/current/ext/hadoop/*,/usr/hdp/current/tez-client/*,/usr/hdp/current/tez-client/lib/*
