Mridul Muralidharan commented on PIG-788:
-----------------------------------------
We do use floats quite a bit in our projects, so assertion of "we do not see
anyone using the float type" is not correct.
Even the webdata (and webmap too iirc) uses float for some of its fields.
Agree with rest of Santhosh' comments above (11/May/09 05:52 PM) too.
> Proposal to remove float from Pig data types
> --------------------------------------------

> Key: PIG-788
> URL: https://issues.apache.org/jira/browse/PIG-788
> Project: Pig
> Issue Type: Improvement
> Components: impl
> Affects Versions: 0.2.0
> Reporter: Alan Gates
> Assignee: Alan Gates
>
> Pig would like to use the new Hadoop Avro serialization package to pass data
> between MR jobs, and eventually between Pig and UDFs that are not written in
> Java. Avro will not be supporting the float data type, but only double (see
> AVRO-17). Pig currently support both float and double. Double is the
> default floating point type (so if the user says x + 1.0, 1.0 is taken to be
> a double, not a float). Float was initially included in the list of Pig
> types because Hadoop supported it as one of the Writable types, and we were
> trying to make sure all of Hadoop's writable types could be represented in
> Pig.
> In practice we do not see anyone using the float type. In order to be able
> to easily use Avro I propose dropping the float type.
> Please speak up if you are using the float type and you have a compelling
> reason not to use double.
