YCSB error on Hbase

Question

I am trying to get YCSB-0.1.4 to test Hbase 0.98.1 on CDH 5.1.2. I followed instructions here https://github.com/brianfrankcooper/YCSB/wiki/Getting-Started . When I run the YCSB test, it works but its not loading data into the usertable. Do not see any errors in log files.see command below and the operations are zero. How to fix ?

$  bin/ycsb load hbase -P workloads/workloada -p columnfamily=f1 -s | tee -a workloada.dat
YCSB Client 0.1
Command line: -db com.yahoo.ycsb.db.HBaseClient -P workloads/workloada -p columnfamily=f1 -s -load
Loading workload...
Starting test.

Answer 1

When I faced this error, i was working on MultiNode cluster (roughly 12-16) and this is what i had to change :-

1) Check if your HBase version in YCSB\\pom.xml under hbase10\\hbase098\\hbase094 is compatible with HBase version in your Single Node or Multi Node cluster. (look for hbase10.version )

2) Also provide HBase Configuration file path with ycsb command . ex. This is your command :- bin/ycsb load hbase -P workloads/workloada -p columnfamily=f1 -s

It should be like this :- bin/ycsb load hbase -P workloads/workloada -cp $HBase_HOME/conf/-p columnfamily=f1 -s

FYI :- I have not provided configuration file path when i tried with single node cluster and it worked. But with Multi Node cluster i had to give configuration file path.

There is one more thing to look for , usertable should have column family with name f1 (Default is family in workload configuration file)

Hope It helps. :)
