sqoop错误：HADOOP_ORG.APACHE.SQOOP.SQOOP_USER：错误替换

Question

hduser@kubuntu17:~$ sqoop version
/usr/local/hadoop/libexec/hadoop-functions.sh: line 2326: HADOOP_ORG.APACHE.SQOOP.SQOOP_USER: bad substitution
/usr/local/hadoop/libexec/hadoop-functions.sh: line 2421: HADOOP_ORG.APACHE.SQOOP.SQOOP_OPTS: bad substitution

为什么sqoop会抛出此错误以及如何解决？

我已经在hadoop-functions.sh中查看了第2326行，其功能是：

function hadoop_verify_user_perm
{
  declare program=$1
  declare command=$2
  declare uvar

  uvar=$(hadoop_build_custom_subcmd_var "${program}" "${command}" USER)

  if [[ -n ${!uvar} ]]; then
    if [[ ${!uvar} !=  "${USER}" ]]; then
      hadoop_error "ERROR: ${command} can only be executed by ${!uvar}."
      exit 1
    fi
  fi
  return 0
}

对此的任何想法都非常感激。
