Ted Dunning created DRILL-3516: ---------------------------------- Summary: UDF documentation doesn't get people where they need to be Key: DRILL-3516 URL: https://issues.apache.org/jira/browse/DRILL-3516 Project: Apache Drill Issue Type: Bug Reporter: Ted Dunning
The UDF documentation on the web side rooted at http://drill.apache.org/docs/develop-custom-functions/ does not describe the high level process for how UDF's are used, nor does it describe why simple things like toString can't work on *Holder data structures. This leads to huge confusion and frustration on the part of potentially contributors. Here are some pertinent threads: http://mail-archives.apache.org/mod_mbox/drill-user/201507.mbox/%3CCACAwhF%3DBxs-bXNdrm0pNJ4e8hZiaueqtZMhJ%3DRiBpf%3Dt%3DzEOWA%40mail.gmail.com%3E http://mail-archives.apache.org/mod_mbox/drill-user/201507.mbox/%3CCACAwhFmwWkP6udc05UEGFTzpEsaRvAxSRKW%2B2Mg-ijYX8QoQxQ%40mail.gmail.com%3E -- This message was sent by Atlassian JIRA (v6.3.4#6332)
