Ingest Excel file Directly to Hive Table

Sirasit_Mahawanitwong — Sat, 16 Nov 2024 04:37:48 GMT

Hi, I'm fairly new to Talend and I got a task to ingest Excel file directly to Hive table (Hortonworks). I tried with several component like tHiveRow (I don't know the query which will pass my input to the output), tDBOutPut via JDBC (Usually end up with noclassdeffounderror error. I believe it has somethings to do with driver or hive configuration), etc and they didn't work. The only solution I can think is to convert excel file to csv then ingest to Hive. So, my question is, is it possible to ingests Excel file directly to Hive Table without convert the source file? Also, could you guide me which approach should I use for this task?

Thank you

I did try and it actually work..,well for the most part. The result with xls ingestion is not what I expected...here is the result:

However, I tried with .csv file and it worked like a charm!

I suspect that root cause must be how I create the table:

Did I miss something?

Never mind, after I did some research, I came to the conclusion that it is not possible to ingest excel file directly to hive. I have to convert the file to text file before ingestion. Anyway thanks for your help!
