Rsync在没有密码文件的情况下可以通过salt正常运行，但是今天添加密码文件后，它不再起作用：
# salt 10.10.70.202 rsync.rsync rsync://10.10.81.71:9999/test /tmp/test/ delete=True passwordfile=/etc/rsync.passwd
10.10.70.202:
----------
pid:
105711
retcode:
5
stderr:
@ERROR: auth failed on module test
rsync error: error starting client-server protocol (code 5) at main.c(1516) [Receiver=3.0.9]
stdout:
ERROR: Minions returned with non-zero exit code
它正在使用salt rsync模块，通过bash命令运行的结果相同：
# salt 10.10.70.202 cmd.run '/usr/bin/rsync -avz --delete rsync://10.10.81.71:9999/test /tmp/test/ --password-file=/etc/rsync.passwd'
10.10.70.202:
@ERROR: auth failed on module test
rsync error: error starting client-server protocol (code 5) at main.c(1516) [Receiver=3.0.9]
ERROR: Minions returned with non-zero exit code
但是，当我在rsync客户端本地计算机（10.10.70.202）上执行同一命令时，该命令正常工作：
#/usr/bin/rsync -avz --delete rsync://10.10.81.71:9999/test /tmp/test/ --password-file=/etc/rsync.passwd
receiving incremental file list
sent 54 bytes received 108 bytes 324.00 bytes/sec
total size is 0 speedup is 0.00
Rsync服务器配置（10.10.81.71）：
# cat /etc/rsyncd.conf
pid file = /var/run/rsyncd.pid
port = 9999
address = 10.10.81.71
uid = root
gid = root
use chroot = no
read only = no
max connections = 20
lock file = /var/run/rsync.lock
log file = /var/log/rsync.log
#motd file = /etc/rsyncd/rsyncd.motd
timeout = 300
auth users = root
secrets file = /etc/rsyncd.secrets
[test]
path = /tmp/test/
read only = no
# cat /etc/rsyncd.secrets
root:applepen
Rsync客户端配置（10.10.70.202）：
# ls -l /etc/rsync.passwd
-rw------- 1 root root 9 Jul 9 22:47 /etc/rsync.passwd
# cat /etc/rsync.passwd
applepen
当密码不正确时，错误消息与rsync相同，因此我猜想它是否与salt有关，但未读取正确的密码文件内容：
# echo 'foobar' > /etc/rsync.passwd
# /usr/bin/rsync -avz --delete rsync://10.10.81.71:9999/test /tmp/test/ --password-file=/etc/rsync.passwd
@ERROR: auth failed on module test
rsync error: error starting client-server protocol (code 5) at main.c(1516) [Receiver=3.0.9]
我还检查了salt rsync模块，找不到有用的信息。

[更新] 我部署了另一个带有最新Salt版本的Salt环境，仍然可以重现该问题，可能是功能错误，决定将该问题升级到Saltstack。

打开＃48517来跟踪此问题。
答案 0 :(得分：0)
通过设置salt内部的环境变量，salt没有将密码文件内容或环境变量spark_config <- spark_config()
spark_config$spark.executor.memory <- "11G"
spark_config$`sparklyr.shell.driver-memory` <- "11G"
spark_config$spark.dynamicAllocation.enabled <- FALSE
spark_config$`spark.yarn.executor.memoryOverhead` <- "1G"
spark_config$spark.executor.instances <- 32
sc <- spark_connect(master = "yarn-client", config = spark_config)
传递给rsync来解决此问题，这导致rsync身份验证失败。
