I am trying to perform inner join in tMap component while fetching data from tHiveInput component. I am getting data from the main flow as well as the lookup flow but it is failing at join. The data coming from lookup is not more than 100 records. Even if I put a where clause in the tHiveInput query, the component starts giving a NullPointer exception, even if the data is present.
Attaching the job design and the tMap configuration.
At least you have to enter the keys which define global variables used by your lookup table as a filter.
That's probably why you get this error.
In my opinion you should also change the expression "eqq.dataset" by "row9.dataset".
Hope this helps.
Thanks for the response. But can you please elaborate on the first point you mentioned which says, "At least you have to enter the keys which define global variables used by your lookup table as a filter"
