---------------------------------------------------------
Another thing I notice is s3g logs do not show error logs to connect to
previous OM leader host. It may mean that s3g is looking at the correct new om
leader, but the om leader can never be ready.

Another thing I notice is:
> S3 gateway write failure when leader OM is down and OM HA is enabled

> Project: Hadoop Distributed Data Store
> Issue Type: Bug
> Components: om
> Affects Versions: 0.4.0
> Reporter: Li Cheng
> Priority: Major
>
> Use S3 gateway to keep writing data into a specific s3 gateway endpoint.
> After the writer starts to work, I kill the OM process on the OM leader host.
> After that, the s3 gateway can never allow writing data nad keeps reporting
> InternalError for all new coming keys.
