Andrew Purtell commented on HBASE-13647:
----------------------------------------

+1 for revert from 0.98

I will cancel the current RC.

An practically-infinite timeout is a bug by definition. I think we should have 
something like this change in 0.98.13 and the 1.x-es. [~enis], your point about 
the new 60 second default being too aggressive / surprising makes sense. Let's 
reapply to 0.98 and 1.x with a larger default. A reasonable new default could 
be to take the zookeeper timeout and multiply it by 2. Or, we could go with 
another fixed, but larger value, like 5 or 10 minutes. What bothers me is 
INT_MAX, let's not have that.

Regardless I think it would be good if we also file an issue to update the book 
with discussion on zookeeper and RPC timeouts and their relationship.

> Default value for hbase.client.operation.timeout is too high, it is LONG.Max.
> That value will block any service calls to coprocessor endpoints indefinitely.
> Should we introduce better default value for that?
