Is it ok to add more than one node to a exist cluster

2018-06-27 Thread dayu
Hi, I have read a warning of not Simultaneously bootstrapping more than one new node from the same rack in version 2.1 link My cassandra cluster version is 3.0.10. So I wonder to know Is it ok to add more than one node to a exist cluster in 3.0.10. Thanks! Dayu

Thanks for your reply, kurt. another question, Can I bootstrap a new node when some node is in Joining state ? Or I should wait until Joining node becoming Normal ? Dayu At 2018-06-27 17:50:34, "kurt greaves" wrote: Don't bootstrap nodes simultaneously unless you really k

Hi Jeff Thanks for your help. But I didn't remove any tables during bootstrap. I have tried 3 times, still got this error BTW the cassandra version is 3.0.10. dayu ERROR [STREAM-IN-/10.136.71.33] 2018-06-28 08:51:33,330 StreamSession.java:534 - [Stream #712021f0-7a25-11e8

That sound reasonable, I have seen schema mismatch error before. So any advise to deal with schema mismatches? Dayu At 2018-06-28 09:50:37, "Jeff Jirsa" wrote: >That log message says you did: > > CF 53f6d520-2dc6-11e8-948d-ab7caa3c8c36 was dropped during streaming > >

Hi kurt, a rolling restart means run disablebinary, disablethrift, disablegossip, drain, stop cassandra and start cassandra command one by one, right? Only one node is executed at a time Dayu At 2018-06-28 11:37:43, "kurt greaves" wrote: Best off trying a rolling restart.

table named 'dayu' is 123。 because the data in table 'dayu' can be re-generate. I simplly remove dayu_234 folder when rolling restart. Now when running nodetool resetlocalschema, there is no error. and I am bootstrap new node again. I will see is there any other problem left.

Does long latency affect Cassandra's performance

2018-12-15 Thread dayu
Hi all, I am adding a new node to cassandra,but the new node is at different DC,the ping latency between them is 2 ms. I am wondering does the long latency would affect cluster's performance or thoughput? Thank! dayu | | dayu 邮箱:sdycre...@163.com | Signature is customiz

Re: Does long latency affect Cassandra's performance

2018-12-15 Thread dayu
Nitan, thanks for your reply. The new node in different DC is added as same DC, so i mean I use quorum or all for three replicate not local quorum. does the long latency will block coordinate and affect the performance? dayu | | dayu 邮箱:sdycre...@163.com | Signature is customized

https://docs.datastax.com/en/cassandra/3.0/cassandra/operations/opsRepairNodesWhen.html So you means i am misleading by this statements. The full repair only needed when node failure + replacement, or adding a datacenter. right? At 2017-11-02 15:54:49, "kurt greaves" wrote: Where are you se

Thanks for your reply, Blake So what's your advise, as you say the incremental repair has some flaws, should i use it mixed with full repair or just run full repair only ? Dayu At 2017-11-02 20:42:14, "Blake Eggleston" wrote: Because in theory, corruption of your repa
