When I connect a tHiveRow object to anything else (like tLogRow for instance), the job no longer compiles with the following errors:
Exception in thread "main" java.lang.Error: Unresolved compilation problems:
state cannot be resolved or is not a field
name cannot be resolved or is not a field
I have successfully set up a Hive Db Connection, and I can create schemas. But whenever I try to use the schema for anything, no fields can be resolved. I have tested the same table and scenario with the equivalent MySQL database and it was successful.
Any help anyone can give me would be greatly appreciated.
Hi
When you use tHiveRow or tMysqlRow, you'd better create job as follows.
tHiveRow-->tParseRecordSet-->tLogRow
Add a column in tHiveRow and select "Object" data type.
Check Advanced settings-> "Propagate QUERY's recordset" and select the object column.
Retrieve state and name in tParseRecordSet(Set "state" and "name" in Value).
Or you can get a scenario about tParseRecordSet in TOS document.

Hi pedro,
I am trying to extract data from Hive table and see it on console.
My hive table has two columns: key String , value String.
tHiveRow --> tParseRecordSet --> tLogRow
In tHiveRow, In basic settings, I added column result of type object.
QUERY: select key, value from my_table
In Advanced Settings checked box Propagate QUERY's recordset and in use column drop down, selected column result.
In tParseRecordSet did following:
In Prev. Comp. Column list drop down select result
Click sync columns
In Attributes table, provide values for all column names as "key" , "value" , "result"
Output result to tLogRow.
On running, I get this Exception:
Exception in thread "main" java.lang.Error: Unresolved compilation problems:
key cannot be resolved or is not a field
value cannot be resolved or is not a field

Can you tell, what am I missing here.
