Re: Cannot start cassandra node anymore

This is on single node environment, and there is a lot of data in commit logs needs to be flushed to sstables. So remove commit logs will cause data lost. Fortunately, this issue happens on a new key space that have CFs that use composite type, and we can sacrifice loosing data on this new key spa

Re: Tried to restart a node, and now it won't come up

We got the server to start up by applying the patch from the mentioned JIRA, and modified the configuration parameters reader code to set chunk_lenghth_size to null on start so that cassandra will use the default value of 64k. We then deployed the code to the rest of the servers in the cluster, a

Re: Tried to restart a node, and now it won't come up

Looks like this is related to bug in https://issues.apache.org/jira/browse/CASSANDRA-3558. Show schema shows sstable compression chunk_length_kb on the node that the schame was applied is 65536, thought the schema update statement specified chunk_length_kb=64, and on other nodes on the cluster

Re: is there a "no disk storage" mode ?

I am not sure of no disk option, but as for fast unit testing, you can try RAM disk for storage. Huy -- View this message in context: http://cassandra-user-incubator-apache-org.3065146.n2.nabble.com/is-there-a-no-disk-storage-mode-tp7051192p7051728.html Sent from the cassandra-u...@incubator.apa

decommissioned not show being gossipped

Hi, We have 2 nodes have been decommissioned from the cluster running 1.0.3. However, the live nodes still making references to the decommissioned nodes 3 days after the nodes were decommissioned. Nodetool does not show the decommissioned noes. Here are sample log entries: INFO [GossipStage:1]

Re: Added column does not sort as the last column

We don't use subcomparator . We doubled checked comparator, and it look fine. There was typo in my original post. I mean to say upgrade to 1.0.2 from 0.6.13. This issue is now resolved after we upgrade cass to 1.0.3. Thanks! Huy -- View this message in context: http://cassandra-user-incubato
