Hello,
I’ve been trying to get a customer’s 6-blade environment upgraded from VA 6.2 to VA 6.4 and failing. I was hoping some of you could take a look at this, and give me your thoughts on it. I installed a clean 6.4 environment, using an SMU package to transfer all metadata.
Customer uses an SSL reverse proxy, so I updated:
After installing, I logged on to the VA Hub and everything appeared to be running smoothly, however, as soon as I went to the VA Admin page and ‘Manage Servers’ (or any of the other options there), it failed to load or display anything and just gave this pop-up:
Going through the log files, I see this one popping up quite a few times:
[VIEWER ] ERROR [tomcat-http--36] 2014-04-01 11:19:15,801 [ST-32-7uZmnfxNm1P0qKoWtPnN-cas:<username>] mobiledesigner.data.query.LasrQueryRunner - Error of type ServerNotFound.Connection refused
Exception caught in LASRClient (lasr=null, host=<hostname>, port=10010)
java.net.ConnectException: Connection refused

java.net.ConnectException: Connection refused
At first glance I figured there was either something wrong with the LASR license, or with the password used for the sassrv account. Re-applying the license and using the SDM to update the sassrv password didn’t solve anything though.
In the end I reverted the environment back to 6.2 so that the customer could at least go on with their normal production. VA 6.2 is running normally, so the problem must be somewhere in 6.4.
Anyway, that’s the situation. I am very interested in hearing your suggestions or pointers for troubleshooting this issue. Maybe you’ve seen something like this before.
To make your life easier, this is a list of what I have already checked:
And these are my questions:
I would really appreciate some help and/or your thoughts on this.
Kind regards and thanks in advance.

Hey Bram,
we have some similar problems with our Update 6.2 to 6.3 .
As is can see there is a major change between TKGRid and Hadoop. In the 6.2 Installation thers is a TKGrid_2.1 and with 6.3 came up with TKGrid_2.4 and a new directory TKTGDat_2.4 (for text analysis). There are also changes on the hadoop installation between 6.2 and 6.3.
From my point of view you will have to ensure, that your installation is running quite all correct "versions", in all other cases you will have errors. I have just a short look at 6.4 but i think it comes with TKGrid_2.5.
Hope this helps...
Best regards,
Andreas

Hello Andreas,
Thanks for the answer, but I did actually install TKGrid_2.5 prior to migrating the environment to VA 6.4. The one thing that I didn't do here, was update the Hadoop installation.
If anyone can verify that an updated Hadoop is necessary for the migration or that not doing so can cause the issue I mentioned, I would love to know.
Kind regards,
Bram Seldenthuis
We asked Bram to open a Tech Support Track for this.
