[jira] [Created] (DRILL-3138) Doc.: BINARY example "B@e6d9eb7"
doesn't make sense

---------------------------------------------
Summary: Doc.: BINARY example "B@e6d9eb7" doesn't make sense
Key: DRILL-3138
URL: https://issues.apache.org/jira/browse/DRILL-3138
Project: Apache Drill
Issue Type: Bug
Reporter: Daniel Barclay (Drill)
On the Supported Data Types page at http://drill.apache.org/docs/supported-data-types/, the example value of "{{B@e6d9eb7}}" for type {{BINARY}} doesn't make sense.
Strings like "{{[B@e6d9eb7}}" result from calling method {{toString()}} on Java byte arrays (objects of type {{byte[]}} (represented as "{{[B}}" internally). The hex digits represent the hash code of the object.
In particular, those hex digits are not a representation of the BINARY value. They have no relationship to the bytes contained in and the BINARY value represented by the object of type byte[]. (Two different objects containing the same sequence of bytes have different "[B@..." strings.)
The root problem appears to be that our two user interfaces to Drill (SQLLine and the web UI) display such "{{[B@...}}" strings rather than displaying binary string values reasonably.
(They should render a BINARY value into a string of characters that actually represents the string of bytes in the BINARY value (perhaps as a SQL {{<binary string literal>}}).)
