Windows10单节点Hadoop本地文件复制报错：No such file or directory

Hey there, let's work through this HDFS file copy issue together—I've dealt with similar quirks running Hadoop on Windows before, so here's a breakdown of the most likely fixes:

1. Verify Your Local File Path & Current Working Directory #

First off, relative paths like ../my_models/*.model can be tricky in Windows' command line. Let's confirm the basics:

• Open your cmd/PowerShell and run cd (cmd) or Get-Location (PowerShell) to check your current working directory. Calculate if ../my_models actually points to the right folder. For example, if you're in C:\hadoop\bin, ../my_models would be C:\hadoop\my_models—double-check this folder exists and contains your .model files.
• Test if the wildcard works locally first: run dir ../my_models/*.model (cmd) or Get-ChildItem ../my_models/*.model (PowerShell). If this returns "file not found", either the path is wrong, or Windows isn't expanding the * wildcard correctly for Hadoop.

2. Switch to Absolute Paths #

Relative paths are prone to confusion—replace them with full absolute paths to eliminate ambiguity. For example:

hadoop fs -copyFromLocal C:\full\path\to\my_models\*.model hdfs://localhost/tmp

If that still fails, test with a single file first to rule out wildcard issues:

hadoop fs -copyFromLocal C:\full\path\to\my_models\aaa.model hdfs://localhost/tmp

3. Check HDFS Target Path Exists #

While your error points to local files, it's worth confirming the HDFS target isn't the problem. Run this to check if /tmp exists:

hadoop fs -ls hdfs://localhost/tmp

If it doesn't exist, create it first:

hadoop fs -mkdir -p hdfs://localhost/tmp

4. Fix Windows Permissions #

Windows' user permissions can block Hadoop from accessing local files. Try these steps:

• Right-click your command prompt/PowerShell and select Run as administrator, then re-execute the copy command.
• Ensure your current user has read permissions for the my_models folder and all .model files inside it.

5. Work Around Windows Wildcard Limitations #

Windows CMD doesn't expand wildcards like Linux shells do, which can cause Hadoop to receive the literal *.model string instead of the actual file list. Try these alternatives:

• Use PowerShell instead of CMD—it handles wildcards properly and will expand *.model to the actual file names before passing them to Hadoop.
• Manually list all files in the command:

hadoop fs -copyFromLocal ../my_models/aaa.model ../my_models/bbb.model hdfs://localhost/tmp
