Hello Alexey Serbin, Kudu Jenkins,
I'd like you to reexamine a change. Please visit

to look at the new patch set (#4).
Change subject: KUDU-2612 p9: anchor participant ops in WAL
......................................................................
KUDU-2612 p9: anchor participant ops in WAL
Participant ops will now anchor WAL segments in the same way that we
anchor WAL segments for other in-memory state (e.g. MRS, DMS) that gets
rebuilt upon recovery.
Each participant op for a given transaction will update the single
anchor associated with that transaction. As a transaction is
transitioned from state to state, the transaction's prior participant op
is unanchored in favor of anchoring the new op.
Since there currently isn't a need to rid a participant of in-memory
state associated with a transaction, this adds a test-only method to
remove a committed or aborted transaction -- once this method called, a
transaction's anchor is removed and WAL GC may proceed to remove the
latest participant op.
