Thanks Ted.
Basically it's recommended to avoid using RPC calls when writing from
table A to B, having the region in the same RegionServer. There i will
exclude network failures. Am i right?

Table A and B are within the same HBase cluster. Can't guarantee they are
in the same physical machine.
Thanks

Are tables A and B colocated ?
Meaning, is your coprocessor making an RPC call to another server ?

Hi everyone,
Let's say, I have a table(A) where every time I write a coprocessor,
hooked to postPut, writes in other table (B). I can't find anywhere what
happen if the coprocessor fails or can't connect to B
Does the client get aware of that? In case it doesn't, how can i get
noticed about the failure?
Does the Put get rolled back (I think coprocessors works outside row
transaction) ?
Thanks!
Federico
