-------------------------------------

             Summary: Add support of directories & globs to concat
                 Key: AVRO-1787
                 URL: https://issues.apache.org/jira/browse/AVRO-1787
             Project: Avro
          Issue Type: Bug
          Components: java
    Affects Versions: 1.7.7
            Reporter: Cl=C3=A9ment MATHIEU


While answering [this question|http://stackoverflow.com/questions/34856838/=
concat-avro-files-using-avro-tools/34899425#34899425] on stack overflow, I =
noticed that the concat tool does not support directories or glob patterns =
as "input-file".

 OP's use case seems very valid but accepting only files as input push the =
burden on users.

I think that it makes sense to also accept directories as input like cat do=
es. Supporting glob patterns seems also useful if one want to concatenate t=
he output of a MR job (in this case passing the directory won't work becaus=
e of the {{_SUCESS}} file).

I have quickly patched {{concat}} to support files, directories and glob pa=
tterns. Support of glob patterns has been added to {{cat}} since it seems u=
seful too.

This change should not introduce regression for users. But any feedback abo=
ut glob patterns is welcome.
