Ning Zhang commented on HIVE-778:
---------------------------------

The current revision does not support describe function yet. Do you mean the 
annotation like the following in UDFOPDivide.java?

@description(
    name = "/",
    value = "a _FUNC_ b - Divide a by b",
    extended = "Example:\n" +
        "  > SELECT 3 _FUNC_ 2 FROM src LIMIT 1;\n" +
        "  1.5"
)

> add describe div

> Can you add a test which describe div ?
