regardless there is no point using Sqoop for such purpose. it is not really
designed for it :)

Re: Using Sqoop to get data from Impala/Hive to another Hive table

2017-02-21 Thread Jörn Franke
From hive to hive another cluster I would use Hive Import/Export, if possible 
with Falcon instead of Sqoop. Sqoop always needs to do 
serialization/deserialization which is fine if the systems are different (e.g. 
Oracle -> Hive), but if it is the same system then usually it makes sense to 
use the tool of the system (e.g. Hive import/export) for performance/resource 
usage reasons.

Re: Using Sqoop to get data from Impala/Hive to another Hive table

2017-02-21 Thread Mich Talebzadeh
thanks Jorn.

the idea is to test a big data high availability tool. by ingesting data to
the target cluster. I have provisioned aan oracle schema for it so we can
use Sqoop to get data into Hive.

someone suggested try using sqoop to ingest from a hive table in one
cluster to the target cluster.

this is not really a test is iut?

Re: Using Sqoop to get data from Impala/Hive to another Hive table

2017-02-21 Thread Jörn Franke
Hallo,

I have not tried it, but sqoop supports any jdbc driver. However, since the SQL 
syntax is not necessarily standardized you may face issues or performance 
problems. Hive itself has a nice import and export tool that supports also the 
metadata import/export. It can be orchestrated from Oozie and/or Falcon.

Best regards

Using Sqoop to get data from Impala/Hive to another Hive table

2017-02-21 Thread Mich Talebzadeh
Hi,

I have not tried this but someone mentioned that it is possible to use
Sqoop to get data from one Impala/Hive table in one cluster to another?

The clusters are in different zones. This is to test the cluster. Has
anyone done such a thing?

Thanks
