Node fauliure

Hi , I see the node is down with following error while running compute task # A fatal error has been detected by the Java Runtime Environment: # # SIGSEGV (0xb) at pc=0x7facd5cae561, pid=18543, tid=0x7fab8a9ea700 # # JRE version: OpenJDK Runtime Environment (8.0_111-b14) (build 1.8.0_11

Failure to start a bigger ignite cluster.

hi,we have a 4 member ignite cluster starting up well. but when we start extending above and as we add more nodes, we have couple of situations.1. Adding more nodes to the cluster takes time - sometimes upto 180-210seconds.2. Post 7 nodes - we can't add more - nodeCount oscilates between 7 and 6. T

Re: Cache Entries get lost after multiple nodes started ?

Another thing I noticed is that if I stop the node which initially populated the entries, some entries are suddenly lost from the cache. This is really strange to me. Regards, Neeraj On Fri, 24/2/17, Neeraj Vaidya wrote: Subject: Re: Cache Entries

I was able to resolve this after I changed the Key from AffinityUuid to a simple Integer which is auto-incremented. How does one explain the behaviour ? Regards, Neeraj On Fri, 24/2/17, Neeraj Vaidya wrote: Subject: Cache Entries get lost after mul

Cache Entries get lost after multiple nodes started ?

Hi, I have populated a cache containing a K,V pair of . It gets populated fine when I start a single node which is responsible for populating the cache. I am able to retrieve all rows using Zeppelin ignite interpreter or even using web-console. However, when I start another node using the same c

Re: Real-time computing

Thanks Andrey, 1) If I understand correctly, the FailOver feature of the ComputeGrid is to mitigate SPOF for the compute jobs i.e. the Callables/Runnables/Closures which are distributed to multiple nodes. But my goal was also to mitigate the failure of the client node which is responsible for r

Problem is; I have 32GB development box, my test runs that could fit into this much memory I am not able to replicate the issue. it happens on Linux server where I have around 128GB memory. Basically it is not easy to debug. -- View this message in context: http://apache-ignite-users.70518.x6.

Re: Timeout was reached before computation completed

Devis, I think this happens because of thread starvation. Both compute job and service proxy invocations are processed in the same thread pool, so if you synchronously call a service from a job, you can run out of threads and get stuck. Can you replace the service with another callable? In this ca

If you use the same (or default) configuration for the affinity, then the same key in different caches will always end up on the same node. This is guaranteed. D. On Thu, Feb 23, 2017 at 8:09 AM, Andrey Mashenkov < andrey.mashen...@gmail.com> wrote: > Val, > > Yes, with same affinity function en

Re: Real-time computing

Hi Neeraj, 1. Why you want to use Zookeeper to mitigating an SPOF instead of Ignite ComputeGrid failover features? 2. If you need to reuse data then caching makes sense. For processing new entries you can use Events or Continuous queries. You are free in choosing number of nodes for your grid. Yo

Re: QueryCursor with Order by query

Hi Anil, Query initiator node will fetch all records before appling sorting. It is known bug [1], and I hope it will be fixed soon. What about QueryCursor, it is just wrapper that supports query cancellation. Pagination is applied to load map-queries results by reducer in async manner. Looking a

QueryCursor with Order by query

Hi, QueryCursor is used to get the records in pages instead of loading all records into client memory. and I understand that sorting needs to get all the records into client (assuming reducer is client. correct me if i am wrong) memory. How does QueryCursor with sort query behaves ? Thanks. Tha
