Next time please do not set explicit timeout value on test method, the timeout
will be controlled from the framework. If you want to assert the time please
use waitFor to better tell others that this operation is the criminal.
{quote}
Sure [~Apache9]. Thank you for letting me know.

And does this also effect branch-2.1 and branch-2.0?

I think yes. Please let me know if you want this fix in branch-2.1 and
branch-2.0. [~Apache9] [~stack]

> Steps to reproduce are as follows:
> 1. Create a table
> {code}
> create "test", "cf"
> {code}

> snapshot "test", "snap"
> {code}
> 3. Disable the table
> {code}
> disable "test"
> {code}
> 4. Restore the hbase snapshot
> {code}
> restore_snapshot "snap"
> {code}
> 5. Open the table.jsp page for the table in a browser, but it gets stuck
> {code}
> http://<hostname>:16010/table.jsp?name=test
> {code}
> According to the following thread dump, it looks like
> ConnectionImplementation.locateRegionInMeta() gets stuck when getting a
> compaction state.
