Subject [jira] [Commented] (OODT-384) File manager queries not returning expected results unless each product-type has an ingested file and throws exceptions for '*' occurrence in the sql query
Date Thu, 23 Feb 2012 17:12:48 GMT

    [ https://issues.apache.org/jira/browse/OODT-384?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13214860#comment-13214860
] 

Sean Hardman commented on OODT-384:
-----------------------------------

For clarification, this scenario is reproducible (in 0.4-SNAPSHOT) with both the filemgr-client
using the --sqlQuery option and the query_tool using the --sql option.

> Sean Hardman queried the File Manager using the query_tool( on 0.3 and 0.4-SNAPSHOT)
and -sqlQuery options(on 0.4-SNAPSHOT) and found that the query_tool will throw an exception
unless there is a product ingested for each product type listed in the policy.
> The filemgr was queried as follows:
> % ./filemgr-client --url http://localhost:9000 --operation --sqlQuery
> -query "SELECT * FROM *"
> Generates the following on the client side:
> Feb 21, 2012 9:32:29 AM
> org.apache.oodt.cas.filemgr.system.XmlRpcFileManagerClient <init>
> INFO: Loading File Manager Configuration Properties from:
> [../etc/filemgr.properties]
> org.apache.xmlrpc.XmlRpcException: java.lang.Exception:
> org.apache.oodt.cas.filemgr.structs.exceptions.CatalogException: Failed to
> perform complex query : null
> ...
> And generates the following on the server side:
> Feb 21, 2012 9:32:29 AM
> org.apache.oodt.cas.filemgr.repository.XMLRepositoryManager
> getProductTypeByName
> WARNING: XMLRepositoryManager: Unable to find product type: [convert_map
> filemgr filemgr-client migrate_xml_policy query_tool], returning null
> java.lang.NullPointerException
> ...
> It also looks like the query does not read '*' in a query like "SELECT * FROM CatalogFile"
and it throws the following:
> Feb 22, 2012 2:36:52 PM org.apache.oodt.cas.filemgr.system.XmlRpcFileManager complexQuery
> INFO: Query returned 2 results
> org.apache.xmlrpc.XmlRpcException: org.apache.xmlrpc.XmlRpcException: null values not

> 	at org.apache.xmlrpc.XmlRpcClientResponseProcessor.decodeResponse(XmlRpcClientResponseProcessor.java:71)
>         ----

> The sql query returns expected results if elements are individually described like in
"SELECT CAS.ProductName,Filename FROM CatalogFile"
