Mon Aug 7 13:47:55 2017  Santiago_:Good day Everybody
Mon Aug 7 13:48:18 2017  Santiago_:is there any ETL tool for simple loading SQL structured data to Cassandra?
Mon Aug 7 13:52:13 2017  jeffj:Joined the channel
Mon Aug 7 13:55:12 2017  spodkowinski:Santiago_: this should be directed to #cassandra - see Channel guidelines: http://bit.ly/bCbK2R
Mon Aug 7 13:56:33 2017  spodkowinski:https://builds.apache.org/computer/cassandra2/builds - doesn't look good. Can anyone ssh into it and kill any hanging cassandra process?

Mon Aug 7 18:25:58 2017  jeffj_:nice!
Mon Aug 7 18:26:06 2017  urandom:probably wouldn't hurt to send out some more announcements
Mon Aug 7 18:26:53 2017  urandom:and about who we should invite
Mon Aug 7 18:27:11 2017  urandom:in case not everyone is aware, or in case they are unsure if it's For Them

Mon Aug 7 18:59:31 2017  urandom:jeffj_: any other venues you can think of to announce it on?
Mon Aug 7 18:59:52 2017  urandom:social media, mailing lists, etc?
Mon Aug 7 19:00:02 2017  urandom:UCE?
Mon Aug 7 19:00:13 2017  urandom:carrier pigeon?
Mon Aug 7 19:00:40 2017  urandom:a bat signal, maybe?
Mon Aug 7 19:01:40 2017  jayzhuang:Joined the channel
Mon Aug 7 19:02:08 2017  urandom:maybe we can danica patrick to do a tv spot
Mon Aug 7 19:03:01 2017  exlt:bounces cassandra2 slave
Mon Aug 7 19:03:19 2017  urandom:can get, that is...
Mon Aug 7 19:06:29 2017  jeffj_:who runs the @cassandra twitter account? jbellis_ ?
Mon Aug 7 19:06:57 2017  jeffj_:let me poke mcfadin, see if he will tweet from his account, he's got followers too.
Mon Aug 7 19:06:59 2017  urandom:several of us have the login info
Mon Aug 7 19:07:15 2017  urandom:(unless it's been changed)
Mon Aug 7 19:07:32 2017  urandom:i didn't because i didn't want to presume that'd be OK
Mon Aug 7 19:08:09 2017  urandom:can't imagine it wouldn't be, but...
Mon Aug 7 19:08:10 2017  urandom:¯\_(ツ)_/¯
Mon Aug 7 19:09:09 2017  urandom:nope, nm, the password has been changed
Mon Aug 7 19:10:52 2017  exlt:I'm going to cycle through cassandra1-7 slaves and fresh boot all the others, too
Mon Aug 7 19:11:15 2017  exlt:hopes INFRA gets to setting up all the rest of them some time soon
Mon Aug 7 19:11:56 2017  clohfink:how much room is there for ngcc?
Mon Aug 7 19:12:10 2017  clohfink:err whats the capacity
Mon Aug 7 19:13:32 2017  mstepura:Joined the channel
Mon Aug 7 19:23:01 2017  urandom:clohfink: we're starting at 50, but we have room for more
Mon Aug 7 19:23:25 2017  urandom:we wanted to make sure we had the wiggle room to get others in, if for some reason there was a rush
Mon Aug 7 19:24:40 2017  urandom:does anyone understand why JVMInstabilityInspector exec()s jmap to create a heap dump?
Mon Aug 7 19:24:54 2017  urandom:why would that even be necessary?
Mon Aug 7 19:26:09 2017  urandom:afaik, the JVM itself creates a heap dump when so instructed (ala -XX:+HeapDumpOnOutOfMemoryError), how is this not clobbering the JVM created one?
Mon Aug 7 19:27:12 2017  jeffj_:it clobbers it
Mon Aug 7 19:27:17 2017  jeffj_:there's a ticket about it
Mon Aug 7 19:27:30 2017  urandom:oh shit
Mon Aug 7 19:28:07 2017  urandom:does the ticket also mention anything about fork-bombing jmap processes?
Mon Aug 7 19:28:31 2017  jeffj_:#13006 i think
Mon Aug 7 19:28:31 2017  CassBotJr:https://issues.apache.org/jira/browse/CASSANDRA-13006 (Open; Unresolved; 3.0.9): "Disable automatic heap dumps on OOM error"
Mon Aug 7 19:28:34 2017  jeffj_:but jira won't load
Mon Aug 7 19:29:04 2017  urandom:disable automatic?
Mon Aug 7 19:29:27 2017  urandom:i don't understand why we'd do anything other than let the jvm write the heap
Mon Aug 7 19:29:36 2017  urandom:what advantage does exec'ing jmap have?
Mon Aug 7 19:33:00 2017  urandom:ok; the context of the ticket would seem to be "don't do this; just use the jvm mechanisms"
