Failed to set permissions

⚠️ Error (Cygwin / Windows Hadoop Issue)

Usually this error appears when:

Running workflows on Windows
Using Cygwin + Hadoop

📌 Causes

➡️ This error is related to a bug in Hadoop:
👉 HADOOP-7682

The main problem:

Hadoop on Windows (via Cygwin) cannot handle local filesystems properly.
There is a conflict between:
- Hadoop FileSystem
- Windows path
- Cygwin environment

🧠 Impact

Job failed to run
Error while accessing local file
Workflow cannot read/write file

✅ Complete Solution

🔧 1. Copy Patch Library

Copy file:

    patch-hadoop_7682-1.0.x-win.jar

to folder:

    HADOOP_HOME/lib

🔧 2. Add Configuration in core-site.xml

Edit file:

    HADOOP_HOME/conf/core-site.xml

Add:

    <property>
       <name>fs.file.impl</name>
       <value>com.conga.services.hadoop.patch.HADOOP_7682.WinLocalFileSystem</value>
       <description>Enables patch for issue HADOOP-7682 on Windows</description>
    </property>

🔧 3. Run Cygwin as Administrator

➡️ This is important because:

Hadoop requires low-level filesystem access.
Without admin → file access may fail
