I have presto and apache superset hosted at GCP Cloud.
Presto server hosted at http://14.22.122.12:8088/ui/
But when i try to connect Presto to Superset it's giving me this error
Could not load database driver: presto
Already installed the presto driver using pip install pyhive.
Not sure what's wrong here ? My SQLAlchemyURL presto://14.22.122.12:8088/catalog_name
This error usually appears when the driver isn't available (so the connection string format isn't recognized).
I would confirm that the pip install happened correctly. If you're running everything within docker, make sure you rebuilt properly. You can enter the docker cli, fire up a Python shell, and try to import the presto driver (you can also try pip freeze in the docker cli).
I want to connect mssql in my site and it's on CENTOS 6 and I am using PHP 5.5.
Got many solutions online about installing drivers regarding the PDO and ODBC, always getting error of no package found or failed dependencies, don't know why I am not able to install or proceed further.
Any help will be appreciated.
Thanks
If You want to use mssql_connect, You need to install php-mssql from extras repository:
yum install --enablerepo=extras php-mssql
and restart httpd:
service httpd restart
That's it :-)
I have a laravel 5.2 instance configured to run against MS SQL Server. I have downloaded from microsoft the drivers and the connection runs perfect DB::table('usuarios')->select('*')->get(); returns:
[{"id":"5","username":"jtd","password":"$2y$10$t8RXYy\/afaEuIpE8GIk2bOvbHsQoj0fhGPxmo\/3UqJABKVA4I4pHC","email":""}]
But when I try to php artisan migrate i get the:
[PDOException]
could not find driver
Why this is happening?
Stack trace:
c:\wamp\www\presence\webapp>php artisan migrate --verbose
[PDOException]
could not find driver

I found a solution. I post it for everyone. I use WAMP stack (PHP, Apache and MySQL). The fact is that wamp uses the 5.5.12 version for terminal CLI, so I have to install SQL Server PDO Extensions on the version I am using and (besides this) on the 5.5.12 version (I have several PHP versions installed). Can provide more information if needed.
I just successfully installed datastax enterprise 5.0 but I can't get solr running
I got "Connection refused" trying to use
dsetool create_core keyspace.table
Also port 8983 isn't listening
Is there something to do in order to launch the solr service ?
Regards
Yeah if it's a tarball start with dse cassandra -s for search. If it's a package install, edit /etc/defaults/dse to have SOLR_ENABLED=1
Hello and excuse my english.
I'm trying to pull a remote database with heroku, but it gives me this error:
pg_dump: server version: 9.4.5; pg_dump version: 9.3.10
pg_dump: aborting because of server version mismatch
pg_restore: [archiver] input file is too short (read 0, expected 5)
I'm guessing I just need to upgrade my current version 9.3.10 to server version 9.4.5, but is not clear to me how to do it.
PD: I don't mind losing the data of my current databases.
The only solution I found was to completely delete postgresql 9.3 and then installed postgresql 9.4
