由于 VERTEX_FAILURE，Tez DAG 上的 Hive 查询失败未成功

Question

我有 Ambari 2.5.3 和 HDP 2.6.3 的基本设置，并尝试运行下面的一些简单查询。我不明白为什么它失败了。你能帮忙吗？

更新 1

这是我在 Hive 配置中的内容

Answer 1

NPE 可能与 mapred.FileInputFormat 有关。输入格式名称很重要。尝试为 hive.input.format.

设置 org.apache.hadoop.hive.ql.io.HiveInputFormat

设置hive.input.format=org.apache.hadoop.hive.ql.io.HiveInputFormat;

Answer 2

我遇到了同样的问题，把执行引擎改成MR就可以了。
