Mikhail Bautin updated HBASE-6943:
----------------------------------
Description: 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.
Summary: [89-fb] Do not catch certain exceptions trying to get an RS
connection (was: [89-fbDo not catch certain exceptions trying )
> [89-fb] Do not catch certain exceptions trying to get an RS connection
