Hi Manoj,

Are you able to do basic operations with HBase shell? Like scan, put, get, etc.?

WebUI is show tables correctly too?

Yes, it is running fine.

I am using version 0.94.

Thanks,
Manoj

Hi,

I am trying to benchmark hbase with YCSB.

#  ./bin/ycsb load hbase -p columnfamily=family -P workloads/workloada > /tmp/loaddata.tmp

Loading workload...

 Error accessing HBase table: java.io.IOException: Call to <hostname>/<IP>:60020
failed on local exception: java.io.EOFException



HBase+Zookeeper are running fine and i am able to perform other operations on it. The problem
arises only when i use YCSB.



Some background info:

# netstat -ntpl | grep 60020

tcp        0      0 ::ffff: <IP>:60020  :::*                        LISTEN      115262/java



# created user table with,

# hbase org.apache.hadoop.hbase.util.RegionSplitter usertable UniformSplit -c 200 -f family

Hbase related logs doesn't reveal anything.


Can someone point me in the right direction?

Thanks in advance for the help!

-Manoj
