DIH $skipDoc issue
------------------
Key: SOLR-1759
URL: https://issues.apache.org/jira/browse/SOLR-1759
Project: Solr
Issue Type: Bug
Components: contrib - DataImportHandler
Affects Versions: 1.4
Reporter: Gian Marco Tagliani
I'm using the version 1.4.0 of Solr and I'm having some trouble with the DIH
when I use the special command $skipDoc.
After skipping a document to insert, the next one is not inserted in the proper
way.
My DIH configuration is quite complex so I'll try to explain myself with a
simpler example:
item table:
id name
1 aaa
2 bbb
feature table:
Item_id hidden
1 true
2 false
DIH conf:
<document name="products">
<entity name="item" query="select * from item">
<field column="ID" name="id" />
<field column="NAME" name="name" />
<entity name="feature" query="select hidden from feature where
item_id='${item.ID}'">
<field name="$skipDoc" column="hidden" />
</entity>
</entity>
</document>
The result I expected is that the record named "bbb" would be imported, but the
result of my import case is that the other record (the "aaa") has been inserted.
I took a look to the DIH code and I found a possible problem that could cause
this result.
In the DocBuilder class when a $skipDoc is detected, an exception is raised.
After handling the exception another loop starts, without cleaning up the doc
variable.
When the next record is read, the addFieldToDoc method can't fill the doc
fields because they are already filled.
To solve this problem I just clean up the doc variable when handling the
exception.
