1.0.3 cassandra java.lang.AssertionError

[Michael Vaknine]

Hi,
I am running a 4 cluster cassandra with replication factor 3.
I have upgraded to 1.0.3 from 0.7.6
After a week of work I get this errors.
Does someone know what they mean?

Thanks
Michael

Re: Forum and it threads

[Waqar Azeem]

Hi,

'threads' are nested in a 'forum', therefore, I decided to create a
column-family 'thread' with a column named 'parent'.


Is this idea matched with Cassandra philosophy? Because I feel that
extracting the data recursively is computational hungry for a site like
reddit.com.


Therefore one idea is to put the complete data in a JSON and store it in a
single column. I hope the retrieval would be fast but the only glitch is;
writing/inserting the data back to the Cassandra. Would it be time
consuming?

Thanks & Best Regards,
Waqar Azeem

FYI -- BufferOverflowException out of CommitLog on trunk

[Brian O'Neill]

I haven't had time to look into it yet, but just wanted to let you guys
know that I hit this in case someone was in that code.

It happened during a fairly standard load process using M/R.

After that, the server refused to come down with a standard kill.

Forum and it threads

[Waqar Azeem]

Hi,

'threads' are nested in a 'forum', therefore, I decided to create a
column-family 'thread' with a column named 'parent'.


Is this idea matched with Cassandra philosophy? Because I feel that
extracting the data recursively is computational hungry for a site like
reddit.com.


Therefore one idea is to put the complete data in a JSON and store it in a
single column. I hope the retrieval would be fast but the only glitch is;
writing/inserting the data back to the Cassandra. Would it be time
consuming?
