Subject Consistency QUORUM does not work anymore (hector:Could not fullfill request on this host)
Date Tue, 11 Dec 2012 09:13:43 GMT
hi list,

I am using Cassandra with 3 data centers, each DC has more than 10 nodes.

the schema for a keyspace:
{DC1:3, DC2:3, DC3:3}

now, I put some rows using hector with CL Local_Quorum in DC1 ,and then I
get a row with the same CL Local_Quorum in DC1,some exceptions were occured:
Cassandra with dsc-1.0.5, and Hector with 1.1-2.
