HBase Driver for YCSB
This driver is a binding for the YCSB facilities to operate against a HBase Server cluster.
Quickstart
1. Start a HBase Server
You need to start a single node or a cluster to point the client at. Please see Apache HBase Reference Guide for more details and instructions.
2. Set up YCSB
You need to clone the repository and compile everything.
git clone git://github.com/brianfrankcooper/YCSB.git
cd YCSB
mvn clean package
3. Create a HBase table for testing
/HBASE-HOME-DIR/bin/hbase shell
hbase(main):001:0> create 'usertable', 'family'
4. Run the Workload
Before you can actually run the workload, you need to "load" the data first.
You should specify a HBase config directory(or any other directory containing your hbase-site.xml) and a table name and a column family(-cp is used to set java classpath and -p is used to set various properties).
bin/ycsb load hbase -P workloads/workloada -cp /HBASE-HOME-DIR/conf -p table=usertable -p columnfamily=family
Then, you can run the workload:
bin/ycsb run hbase -P workloads/workloada -cp /HBASE-HOME-DIR/conf -p table=usertable -p columnfamily=family
Please see the general instructions in the doc
folder if you are not sure how it all works. You can apply additional properties (as seen in the next section) like this:
bin/ycsb run hbase -P workloads/workloada -cp /HBASE-HOME-DIR/conf -p table=usertable -p columnfamily=family -p clientbuffering=true
Configuration Options
Following options can be configurable using -p.
- clientbuffering : If true, buffer mutations on the client. The default is false.
- writebuffersize : Buffer size to be used when clientbuffering is activated. The default is 12582912(= 1024 * 1024 * 12).
- debug : If true, debugging logs are activated. The default is false.
