> When getting a regionserver connection in 0.89-fb in HBaseClient, we catch
> all types of Throwable. I have observed a real case when the client looked
> stuck. On debugging it turned out that a NoSuchMethodError was thrown and
> caught, leaving the connection in an inconsistent state (initialized socket
> but null streams). All following attempts resulted in NPEs that were also
> caught, and no errors were logged. From the user's perspective the client was
> just stuck. The root cause was the absence of a required jar (hence the
> NoSuchMethodError) but it was not reported properly.
