Fabian Alenius commented on PIG-2684: ------------------------------------- This appears to be limitation in avro itself: [http://avro.apache.org/docs/current/spec.html#Names] The name portion of a fullname, record field names, and enum symbols must: * start with [A-Za-z_] * subsequently contain only [A-Za-z0-9_] The only semi-reasonable solution I can see to this problem is to encode the prefix in the namespace. In record, enum and fixed definitions, the fullname is determined in one of the following ways: * A name and namespace are both specified. For example, one might use "name": "X", "namespace": "org.foo" to indicate the fullname org.foo.X. Anyone have some better idea? > :: in field name causes AvroStorage to fail > ------------------------------------------- > > Key: PIG-2684 > URL: https://issues.apache.org/jira/browse/PIG-2684 > Project: Pig > Issue Type: Bug > Components: piggybank > Reporter: Fabian Alenius > > There appears to be a bug in AvroStorage which causes it to fail when there > are field names that contain :: > For example, the following will fail: > data = load 'test.txt' as (one, two); > grp = GROUP data by (one, two); > result = foreach grp generate FLATTEN(group); > > > store result into 'test.avro' using > org.apache.pig.piggybank.storage.avro.AvroStorage(); > ERROR 2999: Unexpected internal error.
