Question

I am using HBASE 0.94.8 standalone mode in Ubuntu. Its working fine i am able to do every operations in Hbase-shell. But after i logged of my system its giving following err

Answer 1

I've got almost the same error "ZooKeeper exists failed after 4 retries". It was caused by running ./start-hbase.sh without having permissions to connect to the port 2181. The solution turned out to be really simple:

sudo ./start-hbase.sh

I've used the same configuration of hbase-site.xml as it is in Nabeel Ahmed's post.
