为了修复hdfs中的复制文件，我在bash脚本中有以下几行代码
参考-https://community.cloudera.com/t5/community-articles/fix-under-replicated-blocks-in-hdfs-manually/ta-p/244746

su hdfs -c "hdfs fsck / | grep 'Under replicated' | awk -F':' '{print \$1}' > /tmp/under_replicated_files"

  su hdfs -c "for hdfsfile in `cat /tmp/under_replicated_files`; do echo "Fixing $hdfsfile :" ;  hadoop fs -setrep 3 $hdfsfile; done"

脚本在上运行时失败

: ;  hadoop fs -setrep 3 ; done: -c: line 1: syntax error near unexpected token `/user/ambari-qa/.staging/job_1571913174208_0001/job.split'
: ;  hadoop fs -setrep 3 ; done: -c: line 1: `/user/ambari-qa/.staging/job_1571913174208_0001/job.split'

当文件- /tmp/under_replicated_files ，包含：

/user/ambari-qa/.staging/job_1571913174208_0001/job.jar
/user/ambari-qa/.staging/job_1571913174208_0001/job.split
/user/ambari-qa/.staging/job_1571913174208_0003/job.jar

下面这句话我哪里错了？

su hdfs -c "for hdfsfile in `cat /tmp/under_replicated_files`; do echo "Fixing $hdfsfile :" ;  hadoop fs -setrep 3 $hdfsfile; done"

注：
当我在用户手册中执行相同的步骤时- hdfs ，那么我们就没有任何问题了
例子：

su hdfs

$ hdfs fsck / | grep 'Under replicated' | awk -F':' '{print $1}' > /tmp/under_replicated_files
$ for hdfsfile in `cat /tmp/under_replicated_files`; do echo "Fixing $hdfsfile :" ;  hadoop fs -setrep 3 $hdfsfile; done

我们也试过了

su hdfs -c "for hdfsfile in `cat /tmp/under_replicated_files`; do echo \"Fixing $hdfsfile :\" ;  hadoop fs -setrep 3 $hdfsfile; done"

但我们得到：

bash: -c: line 1: syntax error near unexpected token `/user/ambari-qa/.staging/job_1571913174208_0001/job.split'
bash: -c: line 1: `/user/ambari-qa/.staging/job_1571913174208_0001/job.split'
