Kaltura DWH, how force stats update...?

Hi,

Your biggest issue is

2016-03-12 10:36:27 [0.000824] [142.4.193.254] [2073541119] [4] [API] [ks->logError] ERR: exception 'Exception' with message 'Hash
[658d07753e596c42a12e795417026b77f143db60] doesn't match the sha1 on the salt on partner [-1].' in /opt/kaltura/app/infra/log/Kaltu
raLog.php:83

Probably because the secret in /opt/kaltura/app/configurations/batch/batch.ini does not match the actual secret, which you can get with:
mysql> select admin_secret from kaltura.partner where id=-1;

There is also:

#0 /opt/kaltura/app/batch/client/KalturaClient.php(1123): KalturaClientBase->throwExceptionIfError(Array)
--
  thrown in /opt/kaltura/app/batch/client/KalturaClientBase.php on line 362
PHP Fatal error:  Uncaught exception 'KalturaClientException' with message 'couldn't connect to host' in /opt/kaltura/app/batch/cli
ent/KalturaClientBase.php:362

Which you should also look into. Make sure all directives in /opt/kaltura/app/configurations/db.ini point to the correct MySQL and Sphinx hosts.
In particular, make sure:
sphinx1.connection.dsn
and
sphinx2.connection.dsn
both have the Sphinx hosts correctly set. If you only have one Sphinx, point both directives to it.
