Yinghau,
Last week you mentioned that you are running your cluster on EC2 that you shut
them down instance(s) over the weekend.

Since I shutdown the EC2 instance every night, I thought that using
'master','slave1','slave2' will save typing after the full host name change
with reboot.
Hi,

tables. I have configured the cluster in Secure Mode including Secure HBase.
I am running the Job(classical MR job) from a custom client running under user

Hi,
You should consider using Amazon Virtual Private Cloud (VPC) service to
avoid re-assigning IP addresses every time you restart your instances.
Keep in mind limitation of 5 ElasticIPs per VPC.

cluster.
