Re: Cassandra Cluster Admin - phpMyAdmin for Cassandra
Thanks so much SebWajam for this great piece of work!
Is there a way to set a data type for displaying the column names/ values
of a CF ? It seems that your project always uses String Serializer for
any piece of data however most of the times in real world cases this is not
true so can we anyhow configure what serializer to use while reading the
data so that the data may be properly identified by your project &
delivered in a readable format ?

RE: Upgrade Cassandra Cluster to 1.0.3

Hi Jonathan,
You are right I had 1 node 1.0.2 for some reason so I did the upgrade again.
I have now a 4 cluster upgraded to 1.0.3 but now I get the following error
on 2 nodes on the cluster:
ERROR [HintedHandoff:3] 2011-11-23 06:39:31,250 AbstractCassandraDaemon.java

if I did cassandra repair on all the servers on the cluster can I simply
truncate the column family HintsColumnFamily?
Will I lose any data?

This is different an unrelated to hints. What jvm are you using? It
looks like it just simply ran out of stack space, which is odd, but
you can control that with the -Xss option if needed.

Should I have deleted all the hints on all the clustr?
Is 1.0.0 stable enough? I am checking this and don't want to upgrade again
in a week or so.
Thanks

In the meantime you can just delete the hints and rely on read repair
or antientropy repair if you're concerned about the consistency of
your replicas.

You are right this solved the problem.
I do not understand why version 1.0.0 was not affected since I used the same
configuration yaml file.

Upgrade Cassandra Cluster to 1.0.2

Hi,
I would appreciate any help.
I have a cluster of 4 servers with replication factor 3 version 1.0.0
