Error while trying to instert on kudu table

Hi,

We're getting this error message while trying to insert data on a test kudu table.

 

We use Debian 8.5 on all of our servers. and CDH 5.8.1

 

This is the output from impala-shell:

 

[master01:21000] > INSERT INTO my_first_table VALUES (1, "john"), (2, "jane"), (3, "jim");
Query: insert INTO my_first_table VALUES (1, "john"), (2, "jane"), (3, "jim")
ERROR: Kudu features are disabled by the startup flag --disable_kudu.

 

We could not find this flag anywhere on impala config.

Any clues ?

 

Thanks.

Re: Error while trying to instert on kudu table

It sounds like you are not using the special 'IMPALA_KUDU' build of Impala.
The version of Impala that ships with CDH is not equipped to query Kudu,
and you need to download, install, and enable the IMPALA_KUDU parcel in
order to do so. Please check the following link for instructions:

Hi,

 

I'll do that, thanks.

I would say I already checked that doc. And I had the impression that this was only necessary for older versions of Cloudera and Impala. But I cannot find the sentence anymore ...

 

I'll write back with the results.

 

Cheers,

Paco.

Re: Error while trying to instert on kudu table

Hi,

 

I tried to follow the instructions on Impala_kudu installation. But it seems only Ubuntu and RedHat parcels exist.

We use Debian 8.5 in our servers. Is there any chance it could be debian parcels any time soon ?

 

Cheers,

Paco.

I don't think we'll have debian 8 parcels for Impala Kudu anytime soon, no. Sorry!

Re: Error while trying to instert on kudu table

Is there a way we could build our own parcels ?
Maybe using this: https://github.com/cloudera/cm_ext

If so, do you think it would be practical to build impal_kudu parcel for
debian based on ubutu parcel ?

Cheers,
Paco.

Re: Error while trying to instert on kudu table

When the Kudu GA is released then you won't need an IMPALA_KUDU parcel because Kudu will work with the regular Impala parcel at that time, which will support Debian 8. Please check back in the C5.10 timeframe.
