Question

我试过在https://cwiki.apache.org/confluence/display/Hive/Setting+Up+HiveServer2上使用示例但得到以下错误：

/usr/lib/python2.7/dist-packages/pkg_resources.py:1031: UserWarning: /home/dsnadmin/.python-eggs is writable by group/others and vulnerable to attack when used with get_resource_filename. Consider a more secure location (set with .set_extraction_path or the PYTHON_EGG_CACHE environment variable).
  warnings.warn(msg, UserWarning)
Traceback (most recent call last):

thrift.transport.TTransport.TTransportException: Could not start SASL: Error in sasl_client_start (-4) SASL(-4): no mechanism available: No worthy mechs found

这是hive日志：

java.lang.RuntimeException: org.apache.thrift.transport.TSaslTransportException: No data or no sasl data in the stream

有没有人可以帮忙解决问题？非常感谢你。

Answer 1

您缺少某些依赖项，请务必安装cyrus-sasl-devel和cyrus-sasl-gssapi：

在基于RHEL的发行版上：

sudo yum install cyrus-sasl-devel cyrus-sasl-gssapi cyrus-sasl-md5 cyrus-sasl-plain

...或基于Debian的发行版：

sudo apt-get install sasl2-bin libsasl2-2 libsasl2-dev libsasl2-modules

Per @KenKennedy，如果使用GSSAPI进行身份验证，还要添加libsasl2-modules-gssapi-mit包。

Answer 2

1在hive-site.xml中，按以下方式设置配置：

<property>
   <name>hive.server2.authentication</name>
   <value>NOSASL</value>
</property>

2个pyhs2程序代码更改如下：

with pyhs2.connect(host='localhost',
                   port=10000,
                   authMechanism="NOSASL",
                   user='user',
                   password='password',
                   database='default') as conn:

请注意，用户名和密码不能为空，连接到pyhs2时添加任何用户名和密码

Answer 3

上述答案对我的案例不起作用，我也尝试过其他人。最后，我已经解决了我的问题。（不知道它是否适合你）

执行

export LD_LIBRARY_PATH = / usr / lib64：/ usr / local / lib：$ LD_LIBRARY_PATH 在运行脚本之前。

我原来的LD_LIBRARY_PATH是/ usr / local / lib：/ usr / lib64

python无法连接hiveserver2
