Maximum size and number of datafiles
Hello here, Is it possible to tell me if it possible to choose the maximum size for a datafile to prevent fs saturation. When cassandra choose to add a datafile ? Thanks 4 all your answears. Regards, Bonnet Jonathan.
Re: Opscenter Entreprise work without licence ?
Thanks for all who answear me.
Re: Opscenter Entreprise work without licence ?
Nobody to give an answear ?, perhaps i said something stupid :). I Want just a confirmation that opscenter entreprise doesn't work without a licence.
Data File Mechanism
Hello, If possible, i need to know if it's possible to chose how a file *.db can grow, it's limit and the general mechanism about the data files. There is only one file *.db by column familly for one node (except index-filter-statistics-summary) ?, or when the CF grow cassandra add it one more ? Regards, Bonnet Jonathan.
Re: Restore with archive commitlog
Andrey Ilinykh ailinykh at gmail.com writes: As someone told you this feature was added by Netflix to work with Priam (cassandra management tool). Priam itself uses it for several months only, so I doubt if anybody uses this feature in production. Any way, you can ping guys working on Priam. This is your best bet. https://github.com/Netflix/Priam Let us know if you can figure out how to use it. Thank you, Andrey Hello and thanks for answear, The link is not allowed by my company where i Work, so nobody never manage to make work a restore with archive commit log ?

Artur Kronenberg artur.kronenberg at openmarket.com writes: It's been a while since I tried that but here are some things I can think of: * the .log.out seems wrong. Unless your cassandra commitlogs don't end in .log.out. I tried this locally with your script and my commitlogs get extracted to .log files for me. * I never tried the restore procedure on a cluster with multiple nodes. I imagine if you have a quorum defined the replayed commitlog may be ignored because the commitlog write operation is older then the deletion in which case the latter will be returned (nothing in your case) Thanks to take time to answear Artur, When you talkin' about quorum, you think about replication factor or tuneable transaction quorum for consistency ? I work on a multiple node cluster, but for this restore i use a keyspace with no replication on the other node. Regards, Bonnet Jonathan.
Re: Try to configure commitlog_archiving.properties

So when i restore to 2013:12:11 17:00:00 i expect to have my table bein fill up again. The node restart with this config correctly, i see my archive commit log come back to my commitlogdirectory, seems bizarre to me that these ones finish by *.out like CommitLog-3-1386927339271.log.out and not just .log. Everything is normal ? When i query my table now, this one is still empty. Finaly my restore doesn't work and i wonder why ?

So, looking at the code:

I would like someone to confirm that, but it might potentially be a bug.
It does the right thing for an empty restore directory. However it
ignores the fact that the restore command could be empty.
So for you, jonathan, I reckon you have the restore directory set? You
don't need that to be set in order to archive (only if you want to
restore it). So set your restore_directory property to empty and you
should get rid of those errors. The directory needs to be set when you
enable the restore command.
On a second look, I am almost certain this is a bug, as the maybeArchive
command does correctly check for the command to not be empty or null.
The maybeRestore command needs to do the same thing for the
restoreCommand. If someone confirms, I am happy to raise a bug.

In the Home for the old version /produits/cassandra/install_cassandra/apache-cassandra-2.0.0/lib i have: [cassandra at s00vl9925761 lib]$ ls -ltr total 14564 -rw-r- 1 cassandra cassandra 123898 Aug 28 15:07 thrift-server-0.3.0.jar -rw-r- 1 cassandra cassandra 42854 Aug 28 15:07 thrift-python-internal-only-0.7.0.zip -rw-r- 1 cassandra cassandra 55066 Aug 28 15:07 snaptree-0.1.jar -rw-r- 1 cassandra cassandra 1251514 Aug 28 15:07 snappy-java-1.0.5.jar -rw-r- 1 cassandra cassandra 270552 Aug 28 15:07 snakeyaml-1.11.jar -rw-r- 1 cassandra cassandra8819 Aug 28 15:07 slf4j-log4j12-1.7.2.jar -rw-r- 1 cassandra cassandra 26083 Aug 28 15:07 slf4j-api-1.7.2.jar -rw-r- 1 cassandra cassandra 134133 Aug 28 15:07 servlet-api-2.5-20081211.jar -rw-r- 1 cassandra cassandra 1128961 Aug 28 15:07 netty-3.5.9.Final.jar -rw-r- 1 cassandra cassandra 80800 Aug 28 15:07 metrics-core-2.0.3.jar -rw-r- 1 cassandra cassandra 134748 Aug 28 15:07 lz4-1.1.0.jar -rw-r- 1 cassandra cassandra 481534 Aug 28 15:07 log4j-1.2.16.jar -rw-r- 1 cassandra cassandra 347531 Aug 28 15:07 libthrift-0.9.0.jar -rw-r- 1 cassandra cassandra 16046 Aug 28 15:07 json-simple-1.1.jar -rw-r- 1 cassandra cassandra 91183 Aug 28 15:07 jline-1.0.jar -rw-r- 1 cassandra cassandra 17750 Aug 28 15:07 jbcrypt-0.3m.jar -rw-r- 1 cassandra cassandra5792 Aug 28 15:07 jamm-0.2.5.jar -rw-r- 1 cassandra cassandra 765648 Aug 28 15:07 jackson-mapper-asl-1.9.2.jar -rw-r- 1 cassandra cassandra 228286 Aug 28 15:07 jackson-core-asl-1.9.2.jar -rw-r- 1 cassandra cassandra 96046 Aug 28 15:07 high-scale-lib-1.1.2.jar -rw-r- 1 cassandra cassandra 1891110 Aug 28 15:07 guava-13.0.1.jar -rw-r- 1 cassandra cassandra 66843 Aug 28 15:07 disruptor-3.0.1.jar -rw-r- 1 cassandra cassandra 91982 Aug 28 15:07 cql-internal-only-1.4.0.zip -rw-r- 1 cassandra cassandra 54345 Aug 28 15:07 concurrentlinkedhashmap-lru-1.3.jar -rw-r- 1 cassandra cassandra 25490 Aug 28 15:07 compress-lzf-0.8.4.jar -rw-r- 1 cassandra cassandra 284220 Aug 28 15:07 commons-lang-2.6.jar -rw-r- 1 cassandra cassandra 30085 Aug 28 15:07 commons-codec-1.2.jar -rw-r- 1 cassandra cassandra 36174 Aug 28 15:07 commons-cli-1.1.jar -rw-r- 1 cassandra cassandra 1695790 Aug 28 15:07 apache-cassandra-thrift-2.0.0.jar -rw-r- 1 cassandra cassandra 71117 Aug 28 15:07 apache-cassandra-clientutil-2.0.0.jar -rw-r- 1 cassandra cassandra 3265185 Aug 28 15:07 apache-cassandra-2.0.0.jar -rw-r- 1 cassandra cassandra 1928009 Aug 28 15:07 antlr-3.2.jar drwxr-x--- 2 cassandra cassandra4096 Oct 1 14:16 licenses In my new home i have /produits/cassandra/install_cassandra/apache-cassandra-2.0.2/lib: [cassandra at s00vl9925761 lib]$ ls -ltr total 9956 -rw-r- 1 cassandra cassandra 123920 Oct 24 09:21 thrift-server-0.3.2.jar -rw-r- 1 cassandra cassandra 52477 Oct 24 09:21 thrift-python-internal-only-0.9.1.zip -rw-r- 1 cassandra cassandra 55066 Oct 24 09:21 snaptree-0.1.jar -rw-r- 1 cassandra cassandra 1251514 Oct 24 09:21 snappy-java-1.0.5.jar -rw-r- 1 cassandra cassandra 270552 Oct 24 09:21 snakeyaml-1.11.jar -rw-r- 1 cassandra cassandra 26083 Oct 24 09:21 slf4j-api-1.7.2.jar -rw-r- 1 cassandra cassandra 22291 Oct 24 09:21 reporter-config-2.1.0.jar -rw-r- 1 cassandra cassandra 1206119 Oct 24 09:21 netty-3.6.6.Final.jar -rw-r- 1 cassandra cassandra 82123 Oct 24 09:21 metrics-core-2.2.0.jar -rw-r- 1 cassandra cassandra 165505 Oct 24 09:21 lz4-1.2.0.jar -rw-r- 1 cassandra cassandra 217054 Oct 24 09:21 libthrift-0.9.1.jar -rw-r- 1 cassandra cassandra 16046 Oct 24 09:21 json-simple-1.1.jar -rw-r- 1 cassandra cassandra 91183 Oct 24 09:21 jline-1.0.jar -rw-r- 1 cassandra cassandra 17750 Oct 24 09:21 jbcrypt-0.3m.jar
Migration Cassandra 2.0 to Cassandra 2.0.2
Hello, I met some problems during an upgrade version, my source is Cassandra 2.0 and my target is Cassandra 2.0.2. My cluster have 3 nodes in the same datacenter, and i will upgrade them one by one. So i Deploy the binaries of the new version, and configure my cassandra.yaml with the same informations as before. I also make an environnement file like this one (a copy of the old one): export PATH=$PATH:/produits/cassandra/install_cassandra/jre1.7.0_25/bin: /produits/cassandra/install_cassandra/jre1.7.0_25/lib: /produits/cassandra/install_cassandra/apache-cassandra-2.0.2/bin: /produits/cassandra/install_cassandra/apache-cassandra-2.0.2/lib: /produits/cassandra/install_opscenter/opscenter-3.2.0/bin: /produits/cassandra/install_opscenter/opscenter-3.2.0/agent: /usr/local/bin:/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/sbin export JAVA_HOME=/produits/cassandra/install_cassandra/jre1.7.0_25 export CASSANDRA_HOME=/produits/cassandra/install_cassandra/apache-cassandra-2.0.2 export JVM_OPTS=-Dorg.xerial.snappy.tempdir=/produits/cassandra/snappy Nothing change in this 2 files except the new home for Cassandra, i keep the same DATA_FILE_DIRECTORIES,commitlog_directory and saved_caches_directory, same cluster name and same cassandra-topology.properties. I just have change my log4j.appender.R.File=/produits/cassandra/system_log.log in log4j-server.properties. So on the first node i used these commands: nodetool –h 10.250.176.128 disablegossip nodetool –h 10.250.176.128 disablethrift nodetool -h 10.250.176.128 snapshot nodetool -h 10.250.176.128 drain cassandra stop I also comment the num_tokens cause i use vnodes, and decomment initial_token and let a blank for this parameter. Next i load my new environement files, all variables seems correct but when i try to start the node i had these errors. [cassandra@s00vl9925761 conf]$ Error: Could not find or load main class org.apache.cassandra.service.CassandraDaemon I search on the net, and all forums which speak about this error tell me that i have problem with my environment variables. But my variables are all looking good, so i really need help on this. When i come back to the older version, cassandra always start without problems. Thanks.
