Failing tests 2016-08-03 [cassandra-3.9]

2016-08-03 Thread Josh McKenzie 
Summary:
   Somewhat messy day, but I believe things should look less noisy tomorrow
so
   we can get a better view of what we have left to a stable board. Going
to try
   a slightly new format:

[Failures]
   testall:   1
   dtest: 0
   novnode_dtest: 17
   upgrade:   110

[Details]
   testall (1):
  CommitLogSegmentManagerTest.testCompressedCommitLogBackpressure
 CASSANDRA-12283, currently assigned to blerer

   novnode_dtest (17):
  Bulk: Hard to separate signal from noise due to rampant timeouts and
nodes
 being marked down. This is possibly due to a problem in the python
driver
 that was tracked down today - Joel, can you confirm?
 An example message:
('Unable to complete the operation against any hosts', {: ConnectionException('Host has been marked down or
removed',),
: ConnectionException('Host has
been marked down
or removed',), :
ConnectionException('Host has
been marked down or removed',)})
  cql_tests.MiscellaneousCQLTester.prepared_statement_invalidation_test
 **Needs Triage**
 New failure as of yesterday, tracked by CASSANDRA-12361
  materialized_views_test.TestMaterializedViews.complex_repair_test
 Assigned to cyeksigian
 Intermittent failure
 Last comment from Philip indicates we want to move this to
dtest_large. Pinged Jim.

   upgrade (110):
  CASSANDRA-12236 was committed today so that should help with the noise
  Sylvain commented on CASSANDRA-10848 yesterday concerning some
potential
 problems with paging tests and whether or not we're setting the
protocol
 version for those tests. Should be interesting to see how things
look
 after the run with 12236 in.

You could follow the JIRA ticket parent and children, review patches,
etc. :) https://issues.apache.org/jira/browse/CASSANDRA-10989

Re: Massive churn in new SSTables getting generated.

2016-08-03 Thread Rajath Subramanyam 
Hello Cassandra-users / Cassandra-dev,

(Resending with the correct user mailing list)

We have a C* 2.1.12 cluster. We have a total size of ~ 100 GB, with 2-3 GB
of data being pumped in per day. We are encountering an unique situation
where the SSTables are getting compacted (or it seems so) multiple times
within a span of 6 hours time interval. We can conclude this by seeing
different set of generation numbers on the SSTables each time, but with the
same amount of data. Is this a result of compaction or repair ? Or is there
any other operation that can lead to such a situation. The tables are using
STCS.

Thanks in advance for your help.

 - Rajath

Re: C* data validation in new DC

2016-08-03 Thread Romain Hardouin 
Hi, 
Only a repair between each DC (i.e. on the whole cluster) can guarantee that 
your DCs are synced. You can make some checks like data size, estimation of 
number of keys, etc. but it's not accurate at all.
Note: your question is intended to u...@cassandra.apache.org
Best,
Romain

 Hi All

We are running 2.0.14 and recently added new cassandra datacenter to the
existing datacenter. Wondering, if there is a recommended way in cassandra
to check data  completely sync'ed in new datacenter other than *nodetool
cfstats *which just gives estimate of number of keys

Thanks in advance
Ashish
