Subject [jira] [Commented] (AVRO-1924) Variable named 'date' in IDL
Date Fri, 04 Nov 2016 13:48:58 GMT

    [ https://issues.apache.org/jira/browse/AVRO-1924?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15636378#comment-15636378

Zoltan Ivanfi commented on AVRO-1924:
-------------------------------------

Please note that although it may be easy to work around this issue in Parquet, it can happen
in production systems as well, where people may use the name `date` for some fields and have
massive amounts of data and code built around this.

>                 URL: https://issues.apache.org/jira/browse/AVRO-1924
>             Project: Avro

> I was compiling Apache Parquet and found that the switch from Avro 1.8.0 to 1.8.1 broke
their build.
> The error: {code}
> [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]
> {code}
> As it turns out they have a test idl that contains this:
> {code}
> @namespace("org.apache.parquet.avro")
> protocol Cars {
>     record Service {
>         long date;
>     }
> }
> {code}
> 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.
> [~rdblue]: I assigned this to you implemented the mentioned change.
