-------------------------------------------------------------------
Looking at this, this morning I see that we've introduced a number of bugs such
as
* fields for embedded records are now not handled correctly in new GoraCompiler
e.g
{code}
{"name": "protocolStatus", "type": ["null", {
"name": "ProtocolStatus",
"type": "record",
"namespace": "org.apache.nutch.storage",
"fields": [
{"name": "code", "type": "int"},
{"name": "args", "type": {"type": "array", "items": "string"}},
{"name": "lastModified", "type": "long"}
]
}]}
{code}
is simply compiled down into
{code}
{\"name\":\"protocolStatus\",\"type\":[\"null\",\"protocolstatus\"]},
{code}
* additionally fields containing array and map values are now not handled
correctly in GoraCompiler e.g.
{code}
{"name": "headers", "type": {"type": "map", "values": "string"}}
{code}
is incorrectly compiled down into
{code}
{\"name\":\"metadata\",\"type\":\"map\"}
{code}
We need to sort these two cases at a minimum. These are blockers.
I'll work on these two issues and hopefully attach a working v3 patch.
