That sounds like "upgrade to the latest Sun JVM" to me.

Ok then I'll shutdown the server, change the access mode, restart, and
run scrub (and then change the access mode back).
Thanks for the pointers and I'll let you know how it goes one way or the other.

I've also found it useful to disable memmapped file access until the scrub is
complete by adding this to the yaml
disk_access_mode: standard

You should start with scrub.

I'm getting a lot of errors that look something like "java.io.IOError:
java.io.IOException: mmap segment underflow; remaining is 348268797
but 892417075 requested" on one node in a 10 node cluster. I'm
currently running version 0.8.4 but this is data that was carried over
from much earlier version
Look at nodetool getendpoints.

Yes, Aaron that self implemented paging is what I'm trying.
Jonathan, the last column read in the previous result fetched is the starting
column of the next iteration. The end column remains constant. This is using
slice ranges. Afaiu, that should work.

Hi,
I'd like to do $subject. Is there a way to do this?
I feel this should be possible by hashing the key and comparing the token of
each node. But I don't know the internals enough to know exactly?
This is to tell hadoop to fetch a record from a specific node. I'm customizing
the CFIF.

I have had similar experiences. On the advice of the Cassandra team, I now
maintain the queue itself in-memory, but persist the data items in Cassandra
(one per row). When re-starting the system I pull data from Cassandra to
re-construct the ordered queue in-memory. In some cases I write columns to
Yes, the fact that node send TreeRequest (and merkle trees) to themselves is
part of the protocol, no problem there.
As for "it has ran for many hours without repairing anything", what makes you
think it didn't repair anything ?

I have a node in my 0.8.5 ring that I'm attempting to repair. I sent
it the repair command and let it run for a few hours. After checking
the logs it didn't appear to have repaired at all. This was the last
repair-related thing in the logs:

Unfortunately no, because you don't know what the actual
last-column-counted was.

I am using 0.7.4 too. and would waiting for 0.8.6 stable to release because
of CASSANDRA-3166.
did you already using 0.8.6 in production?

What is the implication of having a replication factor greater that the
number of nodes in cluster?
We're changing replication factor at runtime and sometimes when a node is
removed/decomissioned from
the cluster, replication factor will be greater than number of nodes since
we have replication fac

get_count() supports the same predicate as get_slice. So you can implement the
paging yourself.

Is there good reason why cassandra is returning empty rows (no columns)
to client on rangeslicequery? (list command in CLI). They should be
hidden from user because it confuses applications.
They are not returned if get CLI command is used.

Do you remember with what version you saw these problems?

The workaround for 0.7 is calling get_slice and count on client side.
It's heavier, sure, but you will then be able to set start column
accordingly.
