Sergei P suggested to send errors when some partitions accept and some refused

Comment by Sergei Petrunia [ 2015-10-13 ]

Correct.
ha_spider::cond_push currently accepts the entire condition always. This means, each partition will have the same condition pushed.

We should add handling for this specific case.
