Hi all,
I got some connection issues between HANA and Cloudera Hadoop/Hive.
Unfortunately, I have to use a newer Version of Hadoop/Hive than the metioned ones of SAP.
The system landscape is Hadoop 2.6 with Hive 1.1.0 on Linux and HANA SPS 09 on Windows.
I've been able to build up a connection via Smart Data Access using the cloudera odbc driver.
The connection is doing fine so far, but the response times of queries is way too Long compared to an iSQL query. Via iSQL the response times for 10 datasets is about 20sec, in HANA the response time is 4min for 10 datasets.
Do you have any idea what's causing the delay?
Or do you have any idea how I can find the cause of the delay?
For me it seems like there are 3 different options:
1. it's an an issue relayed to the supported versions. (but it would be nice to get a confirmation for that)
2. the driver version is not working fine with HANA (I tried different versions of the Hive ODBC driver and also different versions of the Impala driver) (any suggestions which driver/version I should use?)
3. the cause is something I'm not looking at. (any suggestions where to look at or how to trace?)
Does the connection via Smart Data Integration or SAP Data Services work with the mentioned Hadoop/Hive version?
Many thanks for your help!
Best regards
Mo
