Lewis John McGibbney commented on GORA-416:
-------------------------------------------
OK so I've debugged this right through on the
[FetcherJob|https://github.com/apache/nutch/blob/2.x/src/java/org/apache/nutch/fetcher/FetcherJob.java]
task.
What is happening here is that we iterate through the UNION structure of the
[protocolStatus
field|https://github.com/apache/nutch/blob/2.x/src/gora/webpage.avsc#L58-L95]
of the Nutch WebPage object, with the field value at position 1 being created
as **protocolStatus_UnionIndex** and a [subColumn being created as we
desire|https://github.com/apache/gora/blob/master/gora-cassandra/src/main/java/org/apache/gora/cassandra/store/CassandraStore.java#L590].
However once this has been done, when we come to the field value at position 1
we use recursion on
[addOrUpdateField|https://github.com/apache/gora/blob/master/gora-cassandra/src/main/java/org/apache/gora/cassandra/store/CassandraStore.java#L598]
where we then encounter the [RECORD which is the actual
protocolStatus|https://github.com/apache/gora/blob/master/gora-cassandra/src/main/java/org/apache/gora/cassandra/store/CassandraStore.java#L506].
This one contains the actual value.
What happens now is that we [add this as a normal
column|https://github.com/apache/gora/blob/master/gora-cassandra/src/main/java/org/apache/gora/cassandra/store/CassandraStore.java#L512]
instead of the super column that is is defined as.
