我正在aws ec2上运行一个从头开始的集群。我有一个用s3上的数据定义的外部表（分区）。我可以通过简单的select*语句查询此表并将结果接收到控制台：

hive> set hive.execution.engine=tez;
hive> select * from external_table where partition_1='1' and partition_2='2';
<correct results returned>

运行需要tez的查询不会将结果返回到控制台：

hive> set hive.execution.engine=tez;
hive> select count(*) from external_table where partition_1='1' and partition_2='2';
Status: Running (Executing on YARN cluster with App id application_1572972524483_0012)

OK
+------+
| _c0  |
+------+
+------+
No rows selected (8.902 seconds)

但是，如果我在日志和文件系统中挖掘，我可以从该查询中找到结果：

(yarn.resourcemanager.log) org.apache.hadoop.yarn.server.resourcemanager.RMAuditLogger: USER=root     OPERATION=AM Released Container TARGET=SchedulerApp     RESULT=SUCCESS  APPID=application_1572972524483_0022      CONTAINERID=container_1572972524483_0022_01_000002      RESOURCE=<memory:1024, vCores:1>        QUEUENAME=default

SEQ"org.apache.hadoop.io.BytesWritableorg.apache.hadoop.io.Textl▒ꩇ1som}▒▒j¹▒    2060

2060是分区的正确计数。
现在，奇怪的是，如果我在hdfs上插入overwrite目录，我就能从应用程序中得到结果：

hive> set hive.execution.engine=tez;
hive> INSERT OVERWRITE DIRECTORY '/tmp/local_out' select count(*) from external_table where partition_1='1' and partition_2='2';
[root #] hdfs dfs -cat /tmp/local_out/000000_0
2060

但是，尝试插入或覆盖本地目录失败：

hive> set hive.execution.engine=tez;
hive> INSERT OVERWRITE LOCAL DIRECTORY '/tmp/local_out' select count(*) from external_table where partition_1='1' and partition_2='2';
[root #] cat /tmp/local_out/000000_0
cat: /tmp/local_out/000000_0: No such file or directory

如果我对这个查询的容器结果文件进行cat，它只是数字，没有类名或特殊字符：

[root #] cat /tmp/<REALLY LONG FILE PATH>/000000_0
2060

我能找到的唯一不合适的日志消息来自yarn resourcemanager日志：

(yarn.resourcemanager.log) INFO org.apache.hadoop.yarn.server.resourcemanager.RMAuditLogger: USER=root     OPERATION=AM Released Container TARGET=SchedulerApp     RESULT=SUCCESS  APPID=application_1572972524483_0023      CONTAINERID=container_1572972524483_0023_01_000004      RESOURCE=<memory:1024, vCores:1>        QUEUENAME=default

根据最模糊的印象，我猜测结果写入本地文件系统时会出现字符编码问题（因此容器结果文件中会出现特殊字符），但这实际上只是猜测，我不知道如何验证/解决该问题。非常感谢您的帮助！
