我有以下设置：

$ export |grep HADOOP
declare -x HADOOP_HOME="/home/jesaremi/hadoop-3.1.3-bin"
declare -x HADOOP_OPTIONAL_TOOLS="hadoop-azure"

$ echo $PATH
/home/jesaremi/hadoop-3.1.3-bin/bin:/home/jesaremi/hadoop-3.1.3-bin/sbin:/opt/protobuf/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:/home/jesaremi/.dotnet/tools:/opt/HP_Fortify/HP_Fortify_SCA_and_Apps_4.30/bin:/opt/HP_Fortify/HP_Fortify_SCA_and_Apps_4.30/bin

$ ls -l /home/jesaremi/hadoop-3.1.3-bin/share/hadoop/common/

然而，当我尝试计算abfs文件系统的数量时，我得到了以下结果：

$ hdfs dfsadmin -addMount abfs://main@test1.dfs.core.windows.net/ /mnt/abfs/main "fs.azure.abfs.account.name=test1.dfs.core.windows.net,fs.azure.account.key.test1.dfs.core.windows.net=<key removed>"
addMount: java.lang.ClassNotFoundException: Class org.apache.hadoop.fs.azurebfs.AzureBlobFileSystem not found
