shell - Oozie shell 操作

Question

我有一个 oozie shell 操作，它从 HDFS txt 文件获取输入，但每次我调用 txt 文件时，它都说目录不存在，但它存在于服务器上。

这是我的 shell 脚本:

#!/bin/bash

Ingesta="MUM_APPs"
msj="'${1}'"
#alerta=`hdfs dfs -test -e  /user/inpt_red/oozie/workspace/envio_sms/EnviaSMS/Num_Alerta.txt`

while read line
 do
line=${i}
    Num=$(echo $line | cut -d '|' -f1)
    Proceso=$(echo $line | cut -d '|' -f5)

    if [ "$Proceso" == "*" ] || [ "$Proceso" == "$Ingesta" ]; then
        source /user/inpt_red/oozie/workspace/envio_sms/EnviaSMS/EnviaSMS.sh  ${Num} "'ALERTA!!  $Ingesta (`date +%d-%m-%Y` `date +%H:%M:%S`), $msj'"
    fi`enter code here`

done < <(hadoop fs -cat hdfs://mixsfwdebda01.telefonica.com/user/inpt_red/oozie/workspace/envio_sms/EnviaSMS/Num_Alerta.txt)

这是我得到的新错误:

sh: line 17: syntax error near unexpected token `<'
sh: line 17: `done < <(hadoop fs -cat hdfs://mixsfwdebda01.telefonica.com/user/inpt_red/oozie/workspace/envio_sms/EnviaSMS/Num_Alerta.txt)'

或者，您可以将脚本更改为:

hadoop fs -cat hdfs://mixsfwdebda01.telefonica.com/user/inpt_red/oozie/workspace/envio_sms/EnviaSMS/Num_Alerta.txt |\
while read line; do
    echo "${line}"
    #Some Stuff
    #some more stuff
done
