Visitor ID completion does not function properly for a multi-log job. Records that should be added (re-headed) to a session are now possibly treated as a separate session.

In a multi-log job scenario, the Clickstream Parse transformation places incoming records into groups so that the Clickstream Sessionize transformation can run in parallel. If a session record does not have a Visitor ID assigned yet, then the record is grouped according to client IP address and user agent. However, this might be a different group than is calculated using the Visitor ID. When the common groups are merged and passed to the Clickstream Sessionize transformation, the combined group might not contain all the records for a session. All the records that are grouped by Visitor ID might be in one group and those that are grouped by client IP address and user agent might be in a different group.
