No logs directory in apache storm on Mavericks

[Abhishek Raj]

I am using apache-storm 0.9.4 on OS X Mavericks. Here's my 
storm.yamlstorm.zookeeper.servers:
    - "localhost"
storm.zookeeper.port: 2181

storm.local.dir: "/var/lib/storm"
storm.local.hostname: "localhost"

nimbus.host: "localhost"
nimbus.childopts: "-Xmx512m"

supervisor.childopts: "-Xmx256m"
supervisor.slots.ports:
    - 6700
    - 6701
    - 6702
    - 6703

java.library.path: 
"/Library/Java/Extensions:/System/Library/Java/Extensions:/usr/lib/java:/usr/local/lib"

ui.port: 8080

worker.childopts: "-Xmx768m"
I can run nimbus and supervisor fine and can submit topologies as well. But the 
logs directory doesn't appear in storm's folder. I have already verified that 
the folder has apt permissions.
Please help.
Thanks.Abhishek.
