I have to modify the source code of Cassandraļ¼but when I debug the cassandraDaemon suggested by https://cassandra.apache.org/_/development/ide.html , I have this strange error:
`

I'm working on centos7(VM) with idea IntelliJ
In fact, I can run cassandra on command line by using ( ./cassandra) . Anyone know a solution to this problem?
faced with a problem, we have cluster of 5 nodes after restart dse trying to start without success the last record in system.log is below...
Tried with heap and 48 and 64, node has 128GB. Three of them started but these two cannot, no error in the log just that record.

=================
Please advise
Please make sure to use the correct MySQL database connection URL, following the documentation on Driver/Datasource Class Names, URL Syntax and Configuration Properties for Connector/J. In particular, you need to set nullNamePatternMatchesAll=true like this:
schemacrawler.cmd -server=mysql -database=prepaid -infolevel=minimum -command=list -loglevel=CONFIG -url=jdbc:mysql://127.0.0.1:3306/prepaid?nullNamePatternMatchesAll=true -u=root -schemas=prepaid
Or, better, use SchemaCrawler's built-in support for MySQL, like this, which is much easier:
schemacrawler.cmd -server=mysql -host=127.0.0.1 -database=prepaid -infolevel=minimum -command=list -loglevel=CONFIG -u=root -schemas=prepaid

I am unable to connect my Erlang application to Cassandra with ErlCassa. I am getting the following error message:

Erlang version:

I think you need to add this "https://github.com/interline/erlang-thrift" dep into your project.
Because the code of erlcassa tries to use a function "thrift_client_util " of this dep and it can't find it because the dep has not compiled with the project.
During my study of pycassa API i downloaded a sample project Twissandra.
I configured it with cassandra and after login when i ADD tweet the following error occurs ...

Did you modify the Cassandra column families or create them yourself? Maybe you're using an old version of Twissandra?
This particular stacktrace shows that pycassa is expecting a UUID for a column value, but in recent versions of Twissandra, the column values are all BytesType (untyped).
