Hoss Man commented on SOLR-3434:
--------------------------------
bq. but I did have to remove the spaces after the header names
That right there seems to be the crux of hte issue.
The {{header=true}} parsing is working fine, but the devil is in the detail of
the docs for the "trim" option...
http://wiki.apache.org/solr/UpdateCSV#trim
bq. If true remove leading and trailing whitespace from values. ...
...it was only ever designed to trim the _values_, not the names of the fields
in the header.
using the 3.6 example, you can see this clearly with data like...
{noformat}
|foo_s |book_d_i |id |name_id_i
|--------|-----------|-------------|-----------
|20120420| 15600| 2070469502| 12787
|20120420| 64400| 2070469503| 12787
{noformat}
Which, when using header=true, generates a very clear error...
{noformat}
SEVERE: org.apache.solr.common.SolrException: undefined field: "foo_s "
at org.apache.solr.schema.IndexSchema.getField(IndexSchema.java:1261)
at
org.apache.solr.handler.CSVLoader.prepareFields(CSVRequestHandler.java:290)
{noformat}
I suspect the reason the david didn't get this kind of an error with his fields
is because of a {{"\*"}} dynamicField.
I'm not sure that there is really a bug here since it's working as documented,
but i think it would certainly make sense to enhance the handler to also trim
the header if trim=true.
