Wed Oct 12 02:49:39 2016  jeffj:zhaiyuyong: which file? version?
Wed Oct 12 02:53:53 2016  driftx:a quick git grep:

Wed Oct 12 02:55:43 2016  driftx:the two lines before it:

Wed Oct 12 02:55:47 2016  driftx:+ float flushingOffHeap = Memtable.MEMORY_POOL.offHeap.reclaimingRatio();
Wed Oct 12 02:56:04 2016  driftx:if that's not a typo, it needs a comment to explain why
Wed Oct 12 02:57:26 2016  driftx:that was on 2.1, but it looks like it's everywhere

Wed Oct 12 03:31:49 2016  jeffj:like driftx , probably wrong, file a bug.
Wed Oct 12 03:32:00 2016  jeffj:like driftx said, that is
Wed Oct 12 03:32:09 2016  zhaiyuyong:OK thx
Wed Oct 12 03:32:09 2016  driftx:it looks like a mistake, but even if it's somehow not, it's worth a ticket.
Wed Oct 12 03:38:06 2016  zhaiyuyong:thx
Wed Oct 12 03:41:41 2016  driftx:thank you, that's a good catch.

Wed Oct 12 12:58:04 2016  jasobrown:just pulled latest py driver, as well (3.7.0, i believe)
Wed Oct 12 12:58:21 2016  iamaleksey:could be that it's your cqlsh tests that are failing
Wed Oct 12 12:58:26 2016  iamaleksey:they are using bundled by default

Wed Oct 12 12:58:36 2016  jasobrown:stef1927: ahh, ok
Wed Oct 12 12:58:36 2016  iamaleksey:also that.

Wed Oct 12 12:58:55 2016  jasobrown:stef1927: "cassandra-test", that's for the python driver correct?
Wed Oct 12 12:58:57 2016  stef1927:if you don't have access to the driver repo
Wed Oct 12 12:59:07 2016  jasobrown:i just installed via pip
Wed Oct 12 12:59:10 2016  stef1927:yes that's the branch in the python driver repo

Wed Oct 12 13:00:22 2016  jasobrown:stef1927: ahhh, good to know
Wed Oct 12 13:00:59 2016  jasobrown:it's probably best to just build the python driver locally?
