http://gerrit.cloudera.org:8080/#/c/16526/3/src/kudu/tablet/txn_coordinator.h
File src/kudu/tablet/txn_coordinator.h:

http://gerrit.cloudera.org:8080/#/c/16526/3/src/kudu/tablet/txn_coordinator.h@58
PS3, Line 58:   // TODO(aserbin): document the 'highest_seen_txn_id' parameter
Can this be done in this patch, or is there additional functionality you're 
waiting on?

File src/kudu/transactions/txn_status_manager.cc:

http://gerrit.cloudera.org:8080/#/c/16526/3/src/kudu/transactions/txn_status_manager.cc@164
PS3, Line 164:   // Always set the 'highest_seen_txn_id' on return.
             :   SCOPED_CLEANUP({
             :     if (highest_seen_txn_id) {
             :       std::lock_guard<simple_spinlock> l(lock_);
             :       *highest_seen_txn_id = highest_txn_id_;
             :     }
             :   });
Actually, rather than dropping and re-taking locks via this SCOPED_CLEANUP, how 
would you feel about just explicitly putting these in the below lock_ block. We 
then would also not set this if the tablet isn't loaded.
