stack commented on HBASE-5883:
------------------------------
Should we remove this too?
{code}
+ } else if (ioex.getCause() != null
+ && ioex.getCause() instanceof ConnectException) {
+ ce = (ConnectException) ioex.getCause();
+ ioe = ce;
{code}
If the above happens, we'll get a stack trace that will be missing the last few
stacks; i.e. the difference between here where its handled and wherever
ConnectionException was originally thrown. It could be confuse debugging later?
Also, should we pass the ioe into handleConnectionException? I'd think we'd do
this for the case that ce is null (could that happen)?
Good stuff.
