scala - Apache Livy 不适用于本地 jar 文件

Question

我正在尝试使用 spark-submit 运行本地 jar 文件，它运行良好。这是命令-

spark-submit --class "SimpleApp" --master local myProject/target/scala-2.11/simple-project_2.11-1.0.jar

但是当我尝试使用 curl

curl -X POST --data '{
 "file": "file:///home/user/myProject/target/scala-2.11/simple-project_2.11-1.0.jar",
 "className": "SimpleApp",
}'  
-H 
"Content-Type: application/json" 
http://server:8998/batches

它正在抛出错误

"requirement failed: Local path /home/user/myProject/target/scala-2.11/simple-project_2.11-1.0.jar cannot be added to user sessions."

这是我的 livy.conf 文件，因为一些文章建议更改一些内容。

# What host address to start the server on. By default, Livy will bind to all network interfaces.
livy.server.host = 0.0.0.0

# What port to start the server on.
livy.server.port = 8998

# What spark master Livy sessions should use.
livy.spark.master = local

# What spark deploy mode Livy sessions should use.
livy.spark.deploy-mode = client

# List of local directories from where files are allowed to be added to user sessions. By
# default it's empty, meaning users can only reference remote URIs when starting their
# sessions.
livy.file.local-dir-whitelist= /home/user/.livy-sessions/

这个你能帮我吗。

提前致谢。

我最近从 Apache Livy 获得了本地文件读取的解决方案，因为我使用 cURL 创建了错误的请求。我刚刚用 'local:/' 替换了来自 'file://' 的文件读取协议(protocol)，这对我有用。

curl -X POST --data '{
  "file": "local:/home/user/myProject/target/scala-2.11/simple-project_2.11-1.0.jar",
  "className": "SimpleApp",
}'  
-H 
"Content-Type: application/json" 
http://server:8998/batches

这是一个很小的错误，但仍然无法从 HDFS 访问我的 jar 文件。

谢谢大家帮忙。
