我想在spark应用程序中使用scala的processapi运行一个外部命令。

s"hdfs dfs -cat $folderName$fileName"

当我 spark-submit 对于集群，应用程序可以正常工作，但是 --deploy-mode cluster 它失败了。为什么？
我得到一个错误：

I/O error Pipe closed for process: [hadoop, fs, -cat, /data/test/zipfiletest/pgp_sample_file.PGP]

要执行的整个命令序列如下所示：

val result1 = (s"hdfs dfs -cat $folderName$fileName" #| s"gpg --batch --no-tty --yes --passphrase abcdefgh -d -o /tmp/$paraname")!
val result2 = (s"hadoop fs -put /tmp/$paraname $outputpathwithoutNameService")!
val result3 = (s"rm /tmp/$paraname")!
``` `hdfs dfs -cat /data/test/zipfiletest/pgp_sample_file.PGP` 以及 `gpg` 单独工作很好，似乎问题是管道之间。
