FAQ
Hi Jonathan,

I am again facing an issue with respect to connectivity. This time, i am
trying to connet to impala through Microstrategy and both are available in
AWS. We installed the cloudera connector and tried to access the impala
tables. But we are not able to connect, getting the same error as attached,

Is there a difference in connecting in AWS?
Please verify and let me know the issue.

Thanks for the update Santhakumar. Glad to hear this helped, although it's
interesting that you still needed to change this with 9.3. I'll follow up
with MSTR to see if this is expected behavior.

Yes, as far as I know you should not be seeing this with 9.3. Here's
some follow up from a MSTR resource – see if the following helps, and if
not we'll need to follow up:

If they RMC on the MicroStrategy Database Instance…VLDB
Properties…Report Pre/Post SQL…Pre SQL Statement 5, they should see this
statement in there. They can just blank that out, save and close, restart
I-server and give this a try.


Thanks.

Hi Jonathan,

We are using MSTR version 9.3. So i think there won't be much issue.
Can you please clarify on " the setting ‘Report Pre statement 1’ under
pre/post statements in the MSTR VLDB settings". It would be very much
helpful if you can elaborate a little.

Regards,
San

Santha,

You should be able to fix this by changing the setting ‘Report Pre
statement 1’ under pre/post statements in the MSTR VLDB settings. Note that
this shouldn't be an issue with more recent versions of MSTR, but if you're
using an earlier version than you'll need to modify this setting.

Thanks.
