Change subject: KUDU-2612: acquire and release partition lock ...................................................................... KUDU-2612: acquire and release partition lock This patch plumbs partition locks into participant and write ops for transactional and non-transactional operations. For each transaction, we try to acquire the partition lock in the ParticipantOp prepare phase of BEGIN_TXN and release the lock when COMMIT_TXN or ABORT_TXN is applied. Moreover, we take the partition lock for non-transactional write ops as well to ensure we don’t have duplicate keys. If the partition lock cannot be acquired, the transaction (or write op) is aborted or retried. A flag is also introduced to disable this locking for tests that currently expect support for concurrent transactions.
