Gary Helmling commented on HBASE-5448:
--------------------------------------
[~saint....@gmail.com] That seems an unintentional bug on my part. I recall
that the coprocessorExec() synchronization issue was being fixed at the same
time I was working on this. I might have missed the final resolution. I
probably chose CSLM for "performance" but missed the change in semantics with
disallowing null. With the switch to PB services, you should not get back null
from an endpoint (except with an exception), but that doesn't mean the
Batch.Call implementation wouldn't return null.
