我无法执行 sudo streamsets dc 来启动流集

Question

当我尝试运行:

sudo streamsets dc

我收到以下错误

WARN: could not determine Java environment version; expected 1.8, which are the supported versions
WARN: Security is enabled and was unable to verify policy file 'file:///opt/streamsets-datacollector/etc/sdc-security.policy'

你有什么想法吗？

Answer 1

这可能是一个迟到的答案，但我将其添加以供将来参考。

报错只是说sdc-security.policy文件的路径不对。这样做的原因是您似乎运行来自启用 systemctl 的服务的 streamsets 二进制文件。为了实现这一点，您可以在 shell 的环境变量中设置 StreamSets 的正确路径。我尝试了以下设置，效果很好。

export SDC_CONF=$SDC_DIST/etc/sdc
export SDC_DATA=$SDC_DIST/var/lib/sdc
export SDC_LOG=$SDC_DIST/var/log/sdc
export SDC_HOME=$SDC_DIST/opt/streamsets-datacollector

其中 $SDC_DIST 环境变量定义数据收集器运行时间目录。

然后，您可以启动 sdc 服务：

streamsets dc -verbose

Answer 2

1- 您需要启动流集所在的服务来自后端的命令 --> nohup $SDC_HOME/bin/streamsets dc &

2- 将所有文件从 $SDC_DIST/etc 复制到新创建的 $SDC_CONF 目录。请关注下方 link 了解更多详情 https://streamsets.com/documentation/datacollector/latest/help/datacollector/UserGuide/Installation/Installing_the_DC.html

3- 如果有任何与权限相关的问题，请不要忘记在 sdc-security.policy

的末尾添加这一行

*> // 用户定义的外部目录授权代码库

"file:///opt/sdc-extras/-" { permission java.security.AllPermission; };*
