以编程方式从风暴螺栓中杀死拓扑时编译错误:对象和包同名 [英] Compile Error when killing topology from storm bolt programatically: object and package with same name
问题描述
我正在寻找如何在我的 scala 项目中的风暴 1.2.1
中从风暴螺栓中终止拓扑.从这个answer中,我编写了以下代码:
I was looking for how to kill a topology from a storm bolt in storm 1.2.1
in my scala project.
From this answer, I wrote following code to do it:
private def shutTopology(){
import org.apache.storm.utils.Utils
import org.apache.storm.utils.NimbusClient
val conf = Utils.readStormConfig
val nimbusClient =
NimbusClient.getConfiguredClient(conf).getClient
nimbusClient.deactivate(topology_name)
}
但它给出了以下错误:val conf = Utils.readStormConfig
,如何解决这个问题?
But it given following error in line: val conf = Utils.readStormConfig
, How to resolve this?
错误:(46, 17) 包守护进程包含同名的对象和包:nimbus
Error:(46, 17) package daemon contains object and package with same name: nimbus
其中一个需要从类路径中删除
one of them needs to be removed from classpath
val conf = Utils.readStormConfig
val conf = Utils.readStormConfig
我通过 sbt
和 mvn
编译得到上述错误.我在 here 看到了一些描述,但对如何操作没有太多帮助解决这个问题.
I get above error by compiling via both sbt
and mvn
. I see some description for this here but not much help on how to resolve this.
根据 here 的答案,我能够使用以下方法在 sbt
中编译它scalac
选项:
Based on the answer here, I was able to compile this in sbt
using following scalac
options:
"-Yresolve-term-conflict:object"
我仍然无法完成此操作,如何在使用 maven 编译时解决此错误.
I am stil not able to get this done how to resolve this error when compiling with maven.
推荐答案
根据here的答案,我能够使用以下 scalac 选项在 sbt 中编译它:
Based on the answer here, I was able to compile this in sbt using following scalac options:
"-Yresolve-term-conflict:object"
为了使用 maven 进行编译,我按照建议此处对我的 pom.xml 进行了以下更改:
to get this compiled with maven, I did following changes in my pom.xml as suggested here:
<configuration>
<scalaVersion>${scala.version}</scalaVersion>
<args>
<arg>-Yresolve-term-conflict:object</arg> //this was added
</args>
<jvmArgs>
<jvmArg>-Xms2048m</jvmArg>
<jvmArg>-Xmx4096m</jvmArg>
</jvmArgs>
</configuration>
