环境信息

hadoop 3.1.0

hive-3.1.3

tez 0.9.1

问题描述

可以从hadoop命令行正确地访问s3a uri。我可以创建外部表和如下命令：

create external table mytable(a string, b string) location 's3a://mybucket/myfolder/';
select * from mytable limit 20;

执行正确，但是

select count(*) from mytable;

失败日志：

尝试将core-site.xml中的所有fs.s3a属性添加到tez-site.xml中，并在配置单元会话内设置fs，s3 a，access. key和fs.s3a.secret.key=，但仍出现相同错误。

解决方法

确保未在tez-site.xml中设置tez.use.cluster.hadoop-libs，或者如果设置了，则值应为false
但是当设置为false时，tez无法运行。

当设置为true时，得到了aws凭据错误，即使在每个可能的位置或环境变量中设置了它们。
最终通过将这个属性添加到hive-site.xml中使它工作起来

<property><name>hive.conf.hidden.list</name><value>javax.jdo.option.ConnectionPassword,hive.server2.keystore.password,fs.s3a.proxy.password,dfs.adls.oauth2.credential,fs.adl.oauth2.credential</value>
</property>

这是正确的解决方案。但是，只是让你知道，现在你暴露了S3密钥密码在各种日志文件。一些文件，知道如下;
Hive-〉<HIVE_HOME>/logs/<user>/webhcat/webhcat.log.<date>
Hadoop -〉1个内存6个内存1个
如果您有权访问源代码，则可以修改此方法，使其不在配置单元日志中生成上述属性。
