             Summary: hdfs2 component overwrite option is also being applied to directory filesystem path
                 Key: CAMEL-8768
                 URL: https://issues.apache.org/jira/browse/CAMEL-8768
             Project: Camel
          Issue Type: Bug
          Components: camel-hdfs
    Affects Versions: 2.15.2
            Reporter: Hassan Faouaz
            Priority: Critical


If you need to produce files into an existing HDFS2 path, the default behavoir is overwrite the path, which will delete all existing files on HDFS.  If overwrite option is disabled, then the component will complain that the existing HDFS directory exists and will not work.  

The propose solution is to add the following if statement to ignore check if the HDFS directory exists. The overwrite option should only be used for files not directories.

code snippet in HdfsOutputStream.java:

 if (ret.info.getFileSystem().exists(new Path(ret.actualPath))) {
                //only check of not directory
                if (!ret.info.getFileSystem().isDirectory(new Path(ret.actualPath))) {
                    if (configuration.isOverwrite()) {
                        ret.info.getFileSystem().delete(new Path(ret.actualPath), true);
                    } else {
                        throw new RuntimeCamelException("The file already exists");
                    }
                }
            }
