It seems the type of your id field is integer, but parameter type is string. Can you check it? Please also see if this helps - https://groups.google.com/forum/#!topic/h2-database/fiUw3tqRb1o --Yakov 2016-03-24 11:33 GMT+03:00 16616...@qq.com <16616...@qq.com>: > hi experts, > > I can invoke Sql

Re: Two Ignite Clusters formed after network disturbance

Hi, Correct, the implementations of SegmentationResolver I was referring to are available as a part of GridGain. However you're free to implement your own version of SegmentationResolver and pass it to IgniteConfiguration.setSegmentationResolver(...) upon node startup. Ignite will detect your res

Hi, Java doesn't support "classpath:/" protocol out of the box. This is Spring Framework feature. http://stackoverflow.com/questions/12006602/java-url-protocols-classpath My suggestion is to use plain well-know "file:///" protocol instead. As an example you can refer to ExampleNodeStartup class t

Re: Cache loading errors out

Hi Arthi, Try to use Visual VM Memory Profiler to see the objects that fill the heap [1]. Alternatively you can quickly build a heap histrogram ("jmap -histo ") that will show number of objects of a particular class that are allocated. There is a chance that your custom objects "leaked" somehow.

Re: Ignite server stop unexpectedly

Hi, Looks like you faced split brain situation. Say, you have 3 server nodes - A, B and C. A-B see each other, B-C see each other, but A-C don't. If you shut down node B, then nodes A and C will form two independent clusters which we refer to as "split-brain". Are you sure that all your sever nod

Hi, Possible speedup greatly depends on the nature of your task. Typically, the more MR tasks you have and the more intensively you work with actual data, the bigger improvement could be achieved. Please give more details on what kind of jobs do you run and probably I will be able to suggest somet

Yes, HBase can be also used as a persistence storage. -Val -- View this message in context: http://apache-ignite-users.70518.x6.nabble.com/Is-JDBC-driver-necessary-for-the-storage-used-for-Read-Through-and-Write-Through-tp3650p3672.html Sent from the Apache Ignite Users mailing list archive at

Re: Two Ignite Clusters formed after network disturbance

This is not completely correct. Ignite also lacks the implementation of GridSegmentationProcessor that actually decides whether a segment is valid or not. The implementation of the processor can be injected into Ignite as a part of a plugin. -Val -- View this message in context: http://apache-
