[AVRO-1924] Variable named 'date' in IDL

• Type: Bug

Description

I was compiling Apache Parquet and found that the switch from Avro 1.8.0 to 1.8.1 broke their build.

The error:

[ERROR] Failed to execute goal org.apache.avro:avro-maven-plugin:1.8.1:idl-protocol (schemas) ... 
org.apache.avro.compiler.idl.ParseException: Encountered " "date" "date "" at line 23, column 14.
[ERROR] Was expecting one of:
[ERROR] <IDENTIFIER> ...
[ERROR] "@" ...
[ERROR] "`" ...
[ERROR] -> [Help 1]

As it turns out they have a test idl that contains this:

@namespace("org.apache.parquet.avro")
protocol Cars {
    record Service {
        long date;
    }
}

And this change AVRO-1684 turned the word 'date' into something different for the idl compiler.

So changing the word 'date' into something else fixes the problem.
Yet I think this is an undesirable effect for end user applications.

Ryan Blue: I assigned this to you implemented the mentioned change.
