无法在 Windows 10 机器中启动“Spark 历史服务器”

Question

当尝试使用 Powershell 终端启动 Spark 历史服务器（从我的 SPARK_HOME/sbin）时

.\start-history-server.sh 

使用以下消息启动 Windows 终端，然后关闭。

ps: unknown option -- o
Try `ps --help' for more information.
starting org.apache.spark.deploy.history.HistoryServer, logging to C:\Spark/logs/spark--org.apache.spark.deploy.history.HistoryServer-1-<my-machine>.out
ps: unknown option -- o
Try `ps --help' for more information.
ps: unknown option -- o
Try `ps --help' for more information.
ps: unknown option -- o

Try `ps --help' for more information.

这里是在'C:\Spark\logs'中生成的spark--org.apache.spark.deploy.history.HistoryServer-1-<my-machine>.out中的输出

Spark Command: C:\Program Files (x86)\Java\jre1.8.0_161\bin\java -cp C:\Spark/conf\;C:\Spark\jars\* -Xmx1g org.apache.spark.deploy.history.HistoryServer C:\Spark\logs
========================================
"C:\Program Files (x86)\Java\jre1.8.0_161\bin\java" -cp "C:\Spark/conf\;C:\Spark\jars\*" -Xmx1g org.apache.spark.deploy.history.HistoryServer C:\Spark\logs 
C:\Spark/bin/spark-class: line 96: CMD: bad array subscript

我已经尝试过的：

更新'spark-defaults.conf'如下：

spark.eventLog.enabled           true
spark.eventLog.dir               file:///C:\Spark\logs
spark.history.fs.logDirectory    file:///C:\Spark\logs

[也关注这里的讨论] (cannot start spark history server) 我尝试运行以下命令（来自 SPARK_HOME/sbin）

spark-class org.apache.spark.deploy.history.HistoryServer

但它会导致 FileNotFound 异常如下：（这很奇怪，因为它试图寻找 C:Sparklogs 而不是 C:\Spark\logs）

PS C:\Spark\sbin> spark-class org.apache.spark.deploy.history.HistoryServer                                                                                                                  Using Spark's default log4j profile: org/apache/spark/log4j-defaults.properties

谁能建议我在这里可以尝试什么来解决问题并启动 Spark History 服务器？

谢谢。

更新： 以下工作：

1. 将我的日志“spark.eventLog.dir”和“spark.history.fs.logDirectory”更新为：“file:///C:/Spark/eventlog”
2. 从 SPARKHOME/sbin 执行 Spark-class org.apache.spark.deploy.history.HistoryServer
3. 现在可以从这里访问历史服务器 Web ui：http://localhost:18080
