run YCSB on redis with an error

[kylewu11]

Hi, I am trying to run YCSB to redis. I test the connection with redis.
./bin/ycsb shell redis -p redis.host=localhost -p redis.port=6379
it shows connected.
But when I try to run command './bin/ycsb load redis -s -P workloads/workloada -p "redis.host=127.0.0.1" -p "redis.port=6379" > /home/cc/appResults/load.log'

I get an error as follow:

Anyone knows why this happen? Thanks.

I believe that by default the shell doesn't do anything to connect to a datastore until you give it a command to run.

Could you try running from the 0.15.0 release so that we can eliminate the possibility of something going wrong with running from a source checkout?

The error mentions a redis log; what does it show?
