Since I had to upgrade, I have to fix my Perl client to match the new thrift interface. It'll be later today. Then I can retry. On 10/27/2010 2:09 PM, Jonathan Ellis wrote: > Thanks for the clarification. > > Are you still seeing the tiny files? > > On Wed, Oct 27, 2010 at 4:02 PM, Chip Salzenbe

Thanks for the clarification. Are you still seeing the tiny files? On Wed, Oct 27, 2010 at 4:02 PM, Chip Salzenberg wrote: > That's what you're looking at.  Sorry for the confusion.  I left all the > files in place for the upgrade.  What I meant was that back when b2 was > running, "import" was

That's what you're looking at. Sorry for the confusion. I left all the files in place for the upgrade. What I meant was that back when b2 was running, "import" was how I had created Standard1 in the first place. On 10/27/2010 1:54 PM, Jonathan Ellis wrote: > Sorry, I should have been more clear

Sorry, I should have been more clear: rc1 is upgrade-in-place compatible with b2, so I would have liked to see what the settings were before running it through an export/import cycle. These settings look fine and I doubt you will see bizarre tiny files. On Wed, Oct 27, 2010 at 2:52 PM, Chip Salze

OK, after upgrading to "apache-cassandra-2010-10-27_12-30-38", here's what "show keyspaces" says about the relevant keyspace: ColumnFamily: Standard1 Columns sorted by: org.apache.cassandra.db.marshal.BytesType Row cache size / save period: 0.0/0 Key cache size / save period:

Are these values available in JMX? If so, which ones are they? I'd prefer not to possibly destroy the evidence by upgrading. On 10/27/2010 6:50 AM, Jonathan Ellis wrote: > Connect with the cli and run "show keyspaces." It sounds like > Cassandra somehow picked ludicrously low memtable threshold

Connect with the cli and run "show keyspaces." It sounds like Cassandra somehow picked ludicrously low memtable thresholds. There will be a line like Memtable thresholds: 0.2953125/63/60 This may not be in the b2 cli, in which case you will need to upgrade to the nightly from http://hudso

I should add that the disk free space also changed, so the data directory had a lot more space available than before: /dev/cciss/c0d1 2.8T 202M 2.6T 1% /var/lib/cassandra/data On 10/27/2010 2:17 AM, Chip Salzenberg wrote: > I recently tested 0.7.0beta2 with good results on a reason

I recently tested 0.7.0beta2 with good results on a reasonably powerful machine: 8 Xeon cores (16 if you count hyperthreads), 64G memory, and some nice HP RAID. So far so good. But when I took the same config and moved it to a basically identical box with 128G of memory, cassandra started respond
