DIH transformers cannot reuse output from previous transformations
------------------------------------------------------------------
Key: SOLR-1033
URL: https://issues.apache.org/jira/browse/SOLR-1033
Project: Solr
Issue Type: Improvement
Components: contrib - DataImportHandler
Affects Versions: 1.4
Environment: All operating systems and software platforms
Reporter: Fergus McMenemie
Fix For: 1.4
It can be very useful to reuse the output from a DIH template in other
templates and or regex transformers. Currently this cannot be done. The
resolver is initialized at the start of the transformer run with what ever
values exist for a column name at that instant. As the transformer executes it
may define new values for column names. My change is intended to update the
hash used by the resolver after each successful transformation.
This only applies to the template and regex transformers.
