Re: Failed to wait for initial partition map exchange

Val, It doesn't look like a memory issue.We are using explicit locking (lock entry , do processing and then unlock).Under high load, When we bring down one of the Ignite Server nodes and then again add it back to the cluster,We are getting this issue.We observed the exceptions like Failed to wait

Is there a way to allow nodes to join an already started task?

In the GridGain days I was able to add nodes to an already started task. Is there a way to do that in Ignite? I occasionally have nodes disconnect or crash in a custom native library. I'd like to be able to restart those failed nodes or add additional nodes if the compute isn't progressing

Re: Ignite2.0 memory policy limit

Ajay, I could successfully start a node using your configuration on my laptop. Could you check how many processes are running on your Linux machine and how much physical RAM is left for the Ignite process? You can share the output of “top” or similar tool. Btw, what’s the Linux distribution n

Igfs and MaprFs

Hi, On the ignite site, it does have links that talk about running igfs on top of Apache hadoop, hdp and cdh but there is no mention of MapR ... Is it due to the no namenode architecture of MapR that it is not supported? Pls advise
