以编程方式从风暴螺栓中杀死拓扑时编译错误:具有相同名称的对象和包 [英] Compile Error when killing topology from storm bolt programatically: object and package with same name
问题描述
我一直在寻找如何在我的 Scala 项目中从风暴 1.2.1
中的风暴螺栓中杀死拓扑.从这个答案,我编写了以下代码来做到这一点:
private def ShutTopology(){导入 org.apache.storm.utils.Utils导入 org.apache.storm.utils.NimbusClientval conf = Utils.readStormConfigval nimbusClient =NimbusClient.getConfiguredClient(conf).getClientnimbusClient.deactivate(topology_name)}
但是它给出了以下错误:val conf = Utils.readStormConfig
,如何解决这个问题?
错误:(46, 17) 包守护进程包含同名对象和包:nimbus
其中一个需要从类路径中删除
val conf = Utils.readStormConfig
我通过 sbt
和 mvn
编译得到上述错误.我在此处看到了一些描述,但对如何操作没有太大帮助解决这个问题.
根据答案 here,我能够使用以下内容在 sbt
中编译它scalac
选项:
-Yresolve-term-conflict:object"
在使用 maven 编译时,我仍然无法解决此错误.
根据答案这里,我能够使用以下 scalac 选项在 sbt 中编译它:
"-Yresolve-term-conflict:object"
为了使用 maven 编译它,我按照此处的建议对我的 pom.xml 进行了以下更改:
<预><代码><配置><scalaVersion>${scala.version}</scalaVersion><参数><arg>-Yresolve-term-conflict:object</arg>//这是添加的</args><jvmArgs><jvmArg>-Xms2048m</jvmArg><jvmArg>-Xmx4096m</jvmArg></jvmArgs></配置>I was looking for how to kill a topology from a storm bolt in storm 1.2.1
in my scala project.
From this answer, I wrote following code to do it:
private def shutTopology(){
import org.apache.storm.utils.Utils
import org.apache.storm.utils.NimbusClient
val conf = Utils.readStormConfig
val nimbusClient =
NimbusClient.getConfiguredClient(conf).getClient
nimbusClient.deactivate(topology_name)
}
But it given following error in line: val conf = Utils.readStormConfig
, How to resolve this?
Error:(46, 17) package daemon contains object and package with same name: nimbus
one of them needs to be removed from classpath
val conf = Utils.readStormConfig
I get above error by compiling via both sbt
and mvn
. I see some description for this here but not much help on how to resolve this.
Edit:
Based on the answer here, I was able to compile this in sbt
using following scalac
options:
"-Yresolve-term-conflict:object"
I am stil not able to get this done how to resolve this error when compiling with maven.
Based on the answer here, I was able to compile this in sbt using following scalac options:
"-Yresolve-term-conflict:object"
to get this compiled with maven, I did following changes in my pom.xml as suggested here:
<configuration>
<scalaVersion>${scala.version}</scalaVersion>
<args>
<arg>-Yresolve-term-conflict:object</arg> //this was added
</args>
<jvmArgs>
<jvmArg>-Xms2048m</jvmArg>
<jvmArg>-Xmx4096m</jvmArg>
</jvmArgs>
