这个问题是这个主题的延续.

我遇到的问题是使用Maven打包Scala Spark项目.

当我运行此命令时:

spark-submit --name 28 --master local[2] --class org.test.consumer.TestRunner \
/usr/tests/test1/target/test_service-1.0-SNAPSHOT.jar \
$arg1 $arg2 $arg3 $arg4 $arg5

...,我收到以下错误:

这是我目前pom.xml考虑上面提到的线程的建议(我检查生成的jar包含scala类):

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <groupId>org.test.consumer</groupId>
    <artifactId>test_service</artifactId> …

我有以下数据：

df = data.frame(c("2012","2012","2012","2013"),
                c("tuesday","tuesday","friday","thursday"),
                c("AAA","BBB","AAA","AAA"))
colnames(df) = c("year","day","type")

type我想显示每年和每天值（AAA、BBB）出现的次数（绝对频率） 。目前我编写了以下代码，但它要求我再添加一个维度aes，例如aes(type, some_dimension, fill = as.factor(year))。那么，我怎样才能添加类似的东西count(type)呢？

ggplot(dat) +
  geom_bar(aes(type, fill = as.factor(year)), 
           position = "dodge", stat = "identity") + 
  facet_wrap(~day)

我使用ggplot2库创建了一个饼图，如下所示：

ggplot(dat,
       aes(x = factor(""), fill = workers) ) +
       geom_bar() +
       coord_polar(theta = "y") +
       scale_x_discrete("")

问题是数字 ( count) 显示为2e+05。我怎样才能将它们显示为20000？

更新：

dat <- data.frame(workers=c("Q8","A2","S1","A2","A2","S1"))
