Error occurs when using the query_tool script of the file manager for
a new product type
Hi Everyone,
According to the tutorial
http://oodt.apache.org/components/maven/curator/user/basic.html, I added a
new JSON product type to my file manager. However, if I run the query_tool
script before any json files ingested, it will raise some errors, as shown
here:
$ ./query_tool --url http://localhost:9000 --sql -query "SELECT * FROM JSON"

By the way, if some files with the product type JSON are already ingested
in my file manager, then the query_tool script works very well.
Thanks.

Thanks Angela,
Yes you are using the wrong syntax for Lucene. The syntax should be:
³Fieldname:FieldValue²
Please see the syntax here:
http://lucene.apache.org/core/2_9_4/queryparsersyntax.html
Cheers,
Chris

Re: Error occurs when using the query_tool script of the file manager

Posted by MengYing Wang <me...@gmail.com>.
Hi Prof Chris,
Done with Jira: https://issues.apache.org/jira/browse/OODT-766. This
happens with the SQL Query only, not with the Lucene. At least no exception
is thrown out in Lucene queries.
By the way, maybe I am using the wrong syntax, but it seems the Lucene is
much difficult to use than Sql. For example:
Suppose I have 3 files with the GenericFile type:
$ ./query_tool --url http://localhost:9000 --sql -query "SELECT
CAS.ProductReceivedTime,CAS.ProductName,CAS.ProductId,ProductType,ProductTypeId,ProductTypeName,ProductStructure,Filename,FileLocation,MimeType
FROM GenericFile" -sortBy 'CAS.ProductReceivedTime' -outputFormat
'$CAS.ProductReceivedTime,$CAS.ProductName,$CAS.ProductId,$ProductType,$ProductTypeId,$ProductTypeName,$ProductStructure,$Filename,$FileLocation,$MimeType'

Thanks for reporting this Angela. It would be great if you can
file an issue for this in JIRA? Does this happen with the SQL
Query only, or does it do so also with Lucene?
