ISSUE :Hadoop with HANA using sqoop

samir das mohapatra 2013-02-21, 06:28

Hi All
Can you plese tell me why I am getting error while loading data
from SAP HANA to Hadoop HDFS using sqoop (4.1.2).

Error Log:

The error is truncated, check the actual failed task's logs for complete info:

Caused by: com.sap… what?

Seems more like a SAP side fault than a Hadoop side one and you should
ask on their forums with the stacktrace posted.

Harsh,
   I copied whole logs and past here, It looks like only it is
showing "Caused
by: com.sap" ,
And One thing i did not get is why it is running "SELECT t.* FROM
hgopalan.hana_training AS t WHERE 1=0" . It indicate where 1=0 means no
value . But I database we have records.
Error:

Hey Samir,

Since you've posted this already @CDH users, please go ahead there.

Re: ISSUE :Hadoop with HANA using sqoop

bejoy.hadoop@... 2013-02-21, 07:36

Hi Sameer

The query

"SELECT t.* FROM hgopalan.hana_training AS t WHERE 1=0"

Is first executed by SQOOP to fetch the metadata.

The actual data fetch happens as part of individual queries from each task which would be a sub query of the whole input query.
