Re: Repair Hangs while requesting Merkle Trees

Have you checked the network statistics on that machine? (netstats -tas) while attempting to repair ... if netstats show ANY issues you have a problem. If you can put the command in a loop running every 60 seconds for maybe 15 minutes and post back? Out of curiousity, how many remote DC nodes are

Hi, we are using 2.0.14. We have 2 DCs at remote locations with 10GBps connectivity.We are able to complete repair (-par -pr) on 5 nodes. On only one node in DC2, we are unable to complete repair as it always hangs. Node sends Merkle Tree requests, but one or more nodes in DC1 (remote) never sho

Correct, it's a full tuple comparison. On Wed, Nov 11, 2015 at 1:43 PM, Yuri Shkuro wrote: > Thanks, Tyler. > > I also realized that I misunderstood multi-column restriction. Evidently, > (a, b) > (x, y) does not imply component-wise restriction (a>x && b>y) in > CQL, it only implies full tuple

Thanks, Tyler. I also realized that I misunderstood multi-column restriction. Evidently, (a, b) > (x, y) does not imply component-wise restriction (a>x && b>y) in CQL, it only implies full tuple comparison. That explains why my condition (a, b) > (2, 10) was matching row (2, 11). On Wed, Nov 11,

Re: Multi-column slice restrictions not respected by the returned result

This is a known problem with multi-column slices and mixed ASC/DESC clustering orders. See https://issues.apache.org/jira/browse/CASSANDRA-7281 for details. On Tue, Nov 10, 2015 at 11:02 PM, Yuri Shkuro wrote: > According to this blog: > http://www.datastax.com/dev/blog/a-deep-look-to-the-cql-w

Hello, Reading more codes. I can reproduce the exception. Over long slice parameter can cause the exception. Code : char[] chs = new char[7]; //over 64k Arrays.fill(chs,'b'); String end = String.valueOf(chs); Composite c2 = nameType.make(new Object[] {2, end ,11}); Colu

Re: Cassandra compaction stuck? Should I disable?

Does compactionstats shows only stats for completed compactions (100%)? It might be that the compaction is running constantly, over and over again. In that case I need to know what I might be able to do to stop this constant compaction so I can start a nodetool repair. Note that there is a lot of
