             Summary: Make concat tool handle directories as input
                 Key: AVRO-1909
                 URL: https://issues.apache.org/jira/browse/AVRO-1909
             Project: Avro
          Issue Type: Improvement
          Components: java
    Affects Versions: 1.8.1
            Reporter: Sebastian Wallin
            Priority: Minor


I'm having a situation where I want to concatenate thousands of files in a directory. Currently this generates `Argument list too long` when the shell tries to expand into a list of files.

It would be great for the `concat` tool to handle directories as input for use cases like this, as well as being consistent with the `cat` tool

There is a similar issue filed (AVRO-1787), which requests both directories and glob patters to be handled. IMHO it would be enough to make the `concat` tool handle directories, as a start. It would also require a lot less code to be changed.
