src/log/recover.cpp <https://reviews.apache.org/r/15802/#comment60692> Scenarios: (1) A and B and C all in VOTING, adding D, quorum of size 2: D goes into RECOVERING, recovers then goes into VOTING. (2) A and B in VOTING, adding D, quorum size of 2: D goes into RECOVERING, recovers then goes into VOTING. (3) A in VOTING, adding D, quorum size of 2: D tries to recover forever. (4) A in VOTING and B in EMPTY, adding D, quorum of size 2: D tries to recover forever. (5) A in VOTING and B in STARTING, adding D, quorum of size 2: D goes into VOTING, does not recover from A, B does the same thing. (6) A in VOTING and adding B which was initailized with STARTING, quorum of size 2: B goes into VOTING, does not recover from A. - Benjamin Hindman On Dec. 21, 2013, 9:11 a.m., Jie Yu wrote: > > ----------------------------------------------------------- > This is an automatically generated e-mail.
