If Smart Filters can not be trained on a Squirro installation, this may be due to installing the Squirro storage and cluster nodes in the wrong order. |
Symptoms
You create new Smart Filters with some training. Yet no features are learned, and the "Fingerprint" tab on the advanced settings remains empty.
In the log file /var/log/squirro/fingerprint/fingerprint.log you may see the following error message:
| Code Block |
|---|
WARNING unable to analyze text u'…' for language u'en': IndexOperationError(400, … u'reason': u'failed to find analyzer [en]'}}) |
Solution
To solve this, two Elasticsearch indices have to be re-created: squirro_v7 and squirro_v7_fp.
Run the following commands for both indices. All of these commands are executed on a storage node.
...
Verify, that the index has a problem:
| Code Block |
|---|
$ curl -XGET localhost:9200/{INDEX_NAME}/_settings?pretty=json
{
"squirro_v7_fp" : {
"settings" : {
"index" : {
"creation_date" : "1485956094617",
"number_of_shards" : "3",
"number_of_replicas" : "0",
"uuid" : "DAMCDUeBTGKgEUEK1Mx9fQ",
"version" : {
"created" : "2020099"
}
}
}
}
} |
In this example, you get a relatively short output. This indicates, that the configuration is incomplete. If you get a much larger output from this command, your index is most likely fine.
If the previous command confirmed, that there is an issue, then run the following two commands:
