如何设置Storm伪分布式集群(How to set up a Storm pseudo distributed cluster)

我已经设置了Zookeeper伪分布式集群,我想在我的单机上的伪集群上运行Storm拓扑,我该怎么办? 我见过有人写道,需要配置Storm 3次就像处理Zookeeper一样,我不确定,有没有人知道它?


I have set up a Zookeeper pseudo distributed cluster, and I want to run a Storm topology on a pseudo cluster on my single machine, what should I do? I have seen someone write that it need to configure Storm 3 times just like dealing with Zookeeper, I`m not sure, does anyone know about it ?

最满意答案

找:

r'(".*?")|(\s+)'

更换:

r'\1'

我们的想法是忽略引号内的所有字符,首先将所有引号与内部( ".*?" )匹配并替换为相同的( \1 )。

我们知道左边的空格( \s+ )不会在引号内(或者第一个规则会匹配它们)并且不用任何东西替换这些空格。


看到它在行动


Find:

r'(".*?")|(\s+)'

Replace:

r'\1'

The idea is to ignore all characters inside quotes, by first matching all quotes with something inside (".*?") and replacing with the same (\1).

We know that the white spaces left (\s+) will not be inside quotes (or the first rule would have matched them instead) and replace these white spaces with nothing.
