Peter Kovgan updated CASSANDRA-10937:
-------------------------------------
Fix Version/s: (was: 3.0.3)
> OOM on multiple nodes during test of insert load
> ------------------------------------------------
>
> Key: CASSANDRA-10937
> URL: https://issues.apache.org/jira/browse/CASSANDRA-10937
> Project: Cassandra
> Issue Type: Bug
> Environment: Cassandra : 3.0.0
> Installed as open archive, no connection to any OS specific installer.
> Java:
> Java(TM) SE Runtime Environment (build 1.8.0_65-b17)
> OS :
> Linux version 2.6.32-431.el6.x86_64
> ([email protected]) (gcc version 4.4.7 20120313 (Red
> Hat 4.4.7-4) (GCC) ) #1 SMP Sun Nov 10 22:19:54 EST 2013
> We have:
> 8 guests ( Linux OS as above) on 2 VMWare managed physical IBM M6 hosts. Each
> physical host keeps 4 guests.
> Each guest assigned to have:
> 1 disk 300 Gb for seq. log
> 1 disk 4T for data
> 11 CPU cores
> Disks are local, not shared.
> (lshw and cpuinfo attached in file)
> Reporter: Peter Kovgan
> Attachments: more-logs.rar, test2.rar
>
>
> 8 cassandra nodes.
> Load test started with 4 clients(different and not equal machines), each
> running 1000 threads.
> Each thread assigned in round-robin way to run one of 4 different inserts.
> Consistency->ONE.
> I attach the full CQL schema of tables and the query of insert.
> Replication factor - 2:
> create keyspace OBLREPOSITORY_NY with replication =
> {'class':'NetworkTopologyStrategy','NY':2};
> Initiall throughput is:
> 215.000 inserts /sec
> or
> 54Mb/sec, considering single insert size a bit larger than 256byte.
> Data:
> all fields(5-6) are short strings, except one is BLOB of 256 bytes.
> After about a 2-3 hours of work, I was forced to increase timeout from 2000
> to 5000ms, for some requests failed for short timeout.
> Later on(after aprox. 12 hous of work) OOM happens on multiple nodes.
> (all failed nodes logs attached)
> I attach also example java load client.
> Attachments:
> test2.rar -contains most of material
> more-logs.rar - contains additional nodes logs
