Connecting to 192.168.139.132:8081... failed: Connection refused.

该错误提示表明连接被拒绝，可能是由于以下原因导致的：

1. 目标主机未启动或未运行服务。
2. 目标主机的防火墙阻止了连接。
3. 网络连接存在问题。

为了解决这个问题，可以尝试以下几个步骤：

1. 确认目标主机已经启动，并且正在运行需要连接的服务。
2. 检查目标主机的防火墙设置，确保允许连接的端口已经打开。
3. 检查网络连接是否正常，可以尝试使用ping命令测试网络连接是否正常。

如果以上步骤都没有解决问题，可以尝试使用telnet命令测试连接是否正常。例如，如果要连接到192.168.139.132的8081端口，可以使用以下命令：

telnet 192.168.139.132 8081

如果连接成功，将会看到类似以下的输出：

Trying 192.168.139.132...
Connected to 192.168.139.132.
Escape character is '^]'.

如果连接失败，则说明存在其他问题，可以进一步排查。

这个错误提示表明无法连接到HiveServer2。可能的原因包括：

1. HiveServer2未启动或未启动成功。可以尝试在服务器上检查HiveServer2的日志文件，查看是否有任何错误或异常。

2. HiveServer2的地址或端口号不正确。请确保URI中的IP地址和端口号与HiveServer2的实际地址和端口号匹配。

3. 防火墙或网络配置阻止了连接。请确保客户端和服务器之间的网络连接正常，并检查防火墙或其他网络配置是否允许连接到HiveServer2的地址和端口号。

你可以先尝试检查以上可能的原因，以确定问题的具体原因。

Liveness probe failed: Get "https://192.168.58.3:8443/livez": dial tcp 192.168.58.3:8443: connect: connection refused

This error message indicates that the liveness probe for a Kubernetes container has failed. The liveness probe is a mechanism that Kubernetes uses to check if a container is running as expected. In this case, the probe failed because Kubernetes was unable to establish a connection to the container at the specified IP address and port.

There could be several reasons why Kubernetes was unable to connect to the container. One possibility is that the container is not running or has crashed. Another possibility is that there is a firewall or network configuration issue preventing the connection.

To troubleshoot this issue, you can start by checking the logs for the container to see if there are any error messages indicating why it failed. You can also try connecting to the container manually using the IP address and port specified in the error message to see if there are any network issues. Additionally, you can check the Kubernetes configuration to ensure that the container is configured correctly and that there are no firewall or network issues preventing the connection.
