Hello, All,
I can't find the way to change uniqueKey in "managed-schema" environment!!!
my steps:
1. Solr 5.3.1
/opt/solr/bin/solr start
/opt/solr/bin/solr create -c my_mail
2. added a few fields:
curl -X POST -H 'Content-type:application/json' --data-binary '{
"add-field":{"name":"sentDate", "type":"date", "indexed":true,
"stored":true },
"add-field":{"name":"subject", "type":"text_general", "indexed":true,
"stored":true },
...
"add-field":{"name":"flags", "type":"string", "indexed":true,
"stored":true, "omitNorms":true, "multiValued":true },
"add-field":{"name":"messageId", "type":"string", "indexed":true,
"stored":true, "required":true, "multiValued":"false" },
"add-field":{"name":"attachmentNames", "type":"string",
"indexed":true, "stored":true, "omitNorms":true, "multiValued":true }
}' http://localhost:8983/solr/my_mail/schema
3. created according to the docs mail-data-config.xml:
<dataConfig>
<document>
<!--
Note - In order to index attachments, set
processAttachement="true" and drop
Tika and its dependencies to lib directory
-->
<entity processor="MailEntityProcessor"
user="XXXXXXXX"
password="XXXXXXXXX"
host="XXXXXXXXX"
protocol="imaps"
fetchMailsSince="2014-06-30 00:00:00"
batchSize="20"
folders="INBOX"
processAttachement="false"
name="mail_entity"/>
</document>
</dataConfig>
4. put libs paths and requestHandler to solrconfig.xml
...
<lib dir="/opt/solr/contrib/dataimporthandler/lib/" regex=".*\.jar" />
<lib dir="/opt/solr/dist/" regex="solr-dataimporthandler-.*\.jar" />
<lib dir="/opt/solr/contrib/dataimporthandler-extras/lib/"
regex=".*\.jar" />
...
<requestHandler name="/dataimport" class="solr.DataImportHandler">
<lst name="defaults">
<str name="config">mail-data-config.xml</str>
</lst>
</requestHandler>
5. try to dataimport my mailbox
and ... org.apache.solr.common.SolrException: Document is missing
mandatory uniqueKey field: id
6. look at the examples in example/example-DIH/solr/mail/conf
...
<uniqueKey>messageId</uniqueKey>
...
7. The first and the last question: the correct way changing uniqueKey
in schemaless environment? what I missed?
Thanks a lot for everyone for reading and helping.
