-----------------------------------

             Summary: Enforce consistency between maximum RPC size and maximum 
size of transaction
                 Key: KUDU-3023
                 URL: https://issues.apache.org/jira/browse/KUDU-3023
             Project: Kudu
          Issue Type: Improvement
          Components: master, tserver
            Reporter: Alexey Serbin


Current default settings for the {{\-\-rpc_max_message_size}} and the 
{{\-\-tablet_transaction_memory}} (50MB and 64MB correspondingly) might lead to 
situations like described in KUDU-3016.  In other words, a transaction of a 
size between 50 and 64 MBytes can get into the WAL of a leader tablet replica, 
but the leader replica cannot push the corresponding Raft update to follower 
replicas.

It would be nice to establish a group validator to prevent such situations from 
happening.
