Bill Graham commented on PIG-2611:
----------------------------------
I believe that declaring a long an int does not make it an int. It needs to be
casted into one. Do both approaches work if you write output to a file using
{{PigStorage}}?
> HBaseStorage not casting correctly
> ----------------------------------
>
> Key: PIG-2611
> URL: https://issues.apache.org/jira/browse/PIG-2611
> Project: Pig
> Issue Type: Bug
> Affects Versions: 0.9.2
> Environment: Ubuntu 11.10, Hadoop 0.20.2, HBase 0.92.0
> Reporter: David Arthur
> Priority: Minor
> Labels: cast, hbase
>
> When loading data into HBase with HBaseStorage, there is unexpected behavior
> regarding record schema and casting.
> Here is the relevant code snippet:
> {code}
> B = group A by (time_tuple, some_scalar);
> C = foreach B {
> -- UDF to generate id (bytearray)
> generate id, flatten(group.$0), COUNT(A);
> }
> {code}
> At this point the schema for C is unknown, so I declare a schema with a
> foreach statement
> {code}
> D = foreach C generate $0 as id:bytearray, $1 as year:int, $2 as month:int,
> $3 as date:int, $4 as count:int;
> {code}
> Even though I've declared C.$4 as an int, it is still a long (from the
> COUNT). When I go to insert into HBase I get a ClassCastException since the
> schema (int) does not match the actual tuple value (long). I can fix this by
> explicitly casting when I declare the schema.
> {code}
> D = foreach C generate $0 as id:bytearray, $1 as year:int, $2 as month:int,
> $3 as date:int, (int)$4 as count:int;
> {code}
> Is this expected behavior? If not, is this an HBaseStorage issue - not
> honoring the schema before going off casting things?
> Cheers,
> David
