Then we get the support for both Avro and Writable type families. > UUID PType support for Writables > -------------------------------- > > Key: CRUNCH-181 > URL: https://issues.apache.org/jira/browse/CRUNCH-181 > Project: Crunch > Issue Type: Wish > Components: Core > Reporter: Micah Whitacre > Assignee: Josh Wills > Priority: Minor > Attachments: CRUNCH-181.patch > > > UUID is a pretty basic and common datatype used for identifiers. It'd be nice if there was support through Writables.uuids() similar to other common data types. > The lack of support is most likely due to the lack of formal UUIDWritable support in Hadoop itself but a UUIDWritable implementation has been posted for awhile[1] and seems pretty trivial to even roll your own and incorporate. > [1] - https://gist.github.com/stucchio/858014 -- This message is automatically generated by JIRA.
