I am trying to mount and use hdfs using jnr-fuse. but iam getting below error.

-bash: cd: mydirectory: Input/output error

public class HdfsFuseWrapper extends FuseStubFS{

 @Override
public int getxattr(String path, String name, Pointer value, @size_t long size) {
    try {
        // Get the extended attribute from HDFS
        System.out.println("getxpath:"+path+" "+name);
        org.apache.hadoop.fs.FileStatus fileStatus = fileSystem.getFileStatus(new Path(path));
//        String attrValue = fileStatus.getExtendedAttribute(name);
        System.out.println("prin::"+fileStatus.toString());
        String attrValue = "abc";
        if (attrValue == null) {
            return -ErrorCodes.ENODATA(); // No data available error
        }

        // Convert the attribute value to bytes
        byte[] attrBytes = attrValue.getBytes();

        if (attrBytes.length > size) {
            return -ErrorCodes.ERANGE(); // Insufficient buffer error
        }

        // Copy the attribute value to the buffer
        value.put(0, attrBytes, 0, attrBytes.length);

        return attrBytes.length; // Return the length of the attribute value
    } catch (Exception e) {
        return -ErrorCodes.ENOENT(); // File not found error
    }
}

@Override
    public int getattr(String path, FileStat stat) {
        try {
            // Get the file status from HDFS
            org.apache.hadoop.fs.FileStatus fileStatus = fileSystem.getFileStatus(new Path(path));
        System.out.println("permis:"+fileStatus.getPermission());
        // Set the file attributes in the stat structure
            stat.st_mode.set(fileStatus.getPermission().toShort());
            stat.st_nlink.set(1); // Number of hard links
            stat.st_size.set(fileStatus.getLen());

            stat.st_atim.tv_sec.set(fileStatus.getAccessTime()/1000L);
            stat.st_mtim.tv_sec.set(fileStatus.getModificationTime()/1000L);
            //stat.st_mtime.set(fileStatus.getModificationTime() / 1000L); // Convert milliseconds to seconds
            //stat.st_ctime.set(fileStatus.getModificationTime() / 1000L);
            //stat.st_atime.set(fileStatus.getAccessTime() / 1000L);

            return 0; // Success
        } catch (Exception e) {
            return -ErrorCodes.ENOENT(); // File not found error
        }
    }
}

can someone help on this please?

Mounting -
HdfsFuseWrapper wrapper = new HdfsFuseWrapper(hdfsUri);
wrapper.mount(Paths.get(mountPoint), true, true);

-- I tried changing permissions of mounted point in that machine. but not use.

Tried all the options, also checked the net no help from anywhere
