+
+PRs shall not be merged during active, on-topic discussion unless they address
issues such as critical security fixes of a public vulnerability. Under
extenuating circumstances, PRs may be merged during active, off-topic
discussion and the discussion directed to a more appropriate venue. Time should
be given prior to merging for those involved with the conversation to explain
if they believe they are on-topic.

+Lazy consensus requires giving time for discussion to settle while
understanding that people may not be working on Spark as their full-time job
and may take holidays. It is believed that by doing this, we can limit how
often people feel the need to exercise their veto.

+All -1s with justification merit discussion. A -1 from a non-committer can be
overridden only with input from multiple committers, and suitable time must be
offered for any committer to raise concerns. A -1 from a committer who cannot
be reached requires a consensus vote of the PMC under ASF voting rules to
determine the next steps within the [ASF guidelines for code
vetoes](https://www.apache.org/foundation/voting.html).
+
+
+These policies serve to reiterate the core principle that code must not be
merged with a pending veto or before a consensus has been reached (lazy or
otherwise).
+
+
+It is the PMC’s hope that vetoes continue to be infrequent, and when they
occur, that all parties will take the time to build consensus prior to
additional feature work.

+
+Being a committer means exercising your judgement while working in a community
of people with diverse views. There is nothing wrong in getting a second (or
third or fourth) opinion when you are uncertain. Thank you for your dedication
to the Spark project; it is appreciated by the developers and users of Spark.

+
+It is hoped that these guidelines do not slow down development; rather, by
removing some of the uncertainty, the goal is to make it easier for us to reach
consensus. If you have ideas on how to improve these guidelines or other Spark
project operating procedures, you should reach out on the dev@ list to start
