Alan Gates commented on PIG-1985:
---------------------------------
It seems like we're confusing wrong behavior and the solution here. The bug is
that Utils.getSchemaFromString doesn't support the new syntax. It isn't a bug
that it doesn't use the new parser. We can fix this in whatever parser it uses.
I agree that this is a bug against 0.9. It means we didn't fully implement
changes to support typed maps.
> Utils.getSchemaFromString does not use the new parser, and thus fails to
> parse valid schema

> Key: PIG-1985
> URL: https://issues.apache.org/jira/browse/PIG-1985
> Project: Pig
> Issue Type: Bug
> Components: impl
> Affects Versions: 0.9.0
> Reporter: Woody Anderson
> Fix For: 0.10
>
>
> I've been told this is because Utils.getSchemaFromString does not use the new
> parser to parse the schema, so we should update the impl to use the new
> parser:
> {code}
> Utils.getSchemaFromString("f: map[]")
> {code}
> results in: (org.apache.pig.impl.logicalLayer.schema.Schema) {f: map[]}
> {code}
> Utils.getSchemaFromString("f: map[int]")
> {code}
> results in: An exception occurred:
> org.apache.pig.impl.logicalLayer.parser.ParseException
> ..
> org.apache.pig.impl.logicalLayer.parser.ParseException: Encountered " "map"
> "map "" at line 1, column 4.
> Was expecting one of:
> "int" ...
> "long" ...
> "float" ...
> "double" ...
> "chararray" ...
> "bytearray" ...
> "int" ...
> "long" ...
> "float" ...
> "double" ...
> "chararray" ...
> "bytearray" ...
