AW: AssertionError on PasswordAuthenticator

2015-07-28 Thread Andreas Schlüter 
Hi,

 

thanks, that was the issue. I got distracted from too much debugging, when I 
hunted down Usergrid username/password instead of Cassandra Username/Password. 
This way I overlooked the error in simply copying the config file from the link 
that Nate pointed to. One closer look would have sufficed.

 

Thanks for your support anyway.

 

Best,

 

Andreas

Any ideas what might be wrong or which prerequisites need to be met? This is 
the first request for a connection.

 

 

Sam makes a good point. Make sure you have the username and password properties 
set in the configuration file:

https://github.com/apache/incubator-usergrid/blob/master/stack/config/src/main/resources/usergrid-default.properties#L52-L53

 

See this page for details on configuration:

http://usergrid.readthedocs.org/en/latest/deploy-local.html#install-and-configure-cassandra

 

For Usergrid specific questions, feel free to stop by our mail list or IRC 
channel both of which are listed here:

http://usergrid.incubator.apache.org/community/

AssertionError on PasswordAuthenticator

2015-07-25 Thread Andreas Schlüter 
Hi, 

 

I am starting to setup Usergrid on Cassandra, but I run into an issue that I
debugged into and which does not seem to be related to Usergrid or my setup,
since I run into an AssertionError (which should  never happen according to
the comment in the Cassandra Code, and which I don’t see how to avoid from
the client side).

When I do a Login from Usergrid via thrift, I get the following stacktrace:
(Cassandra Version is 2.08, I used the standard username/password
cassandra/cassandra to exclude errors here)

 

ERROR [Thrift:16] 2015-07-25 15:02:32,480 CassandraDaemon.java (line 199)

Any ideas what might be wrong or which prerequisites need to be met? This is

Help would be greatly appreciated, I tried everything I could come up with
supported by Google…

 

Thanks in advance,
