Hi Ivan,
> Run Ignite nodes with -v option and see console logs of the nodes Unfortunately, I can’t run again, it fails. I tried to run on one node with –v option. Logs in attachment. beeline.output <http://apache-ignite-users.70518.x6.nabble.com/file/n12257/beeline.output> default-config.xml <http://apache-ignite-users.70518.x6.nabble.com/file/n12257/default-config.xml> ignite-node.log <http://apache-ignite-users.70518.x6.nabble.com/file/n12257/ignite-node.log> > use IGFS w/o Ignite Map-Reduce, Ignite Map-Reduce w/o IGFS Sorry, I don’t understand, I'm newbie. Could you explain it more detailed? > set -Dignite.job.shared.classloader=false Where I can set it? I don’t know and don't use Java. > Simplest solution is to give Ignite more memory How can I know how much memory Ignite uses? Currently every cluster node has 8 CPU and 16Gb RAM. I tried to add these parameters to default-config.xml: /<property name="memoryMode" value="OFFHEAP_TIERED"/> <property name="offHeapMaxMemory" value="#{4 * 1024L * 1024L * 1024L}"/>/ But then OOM errors arose, so I removed it from config. > In code you can create bean objects (like new FileSystemConfiguration() ) > , then take the values via getters To my shame I don’t know Java. Although I guess that I'm not the only one who does not know Java, but is attracted by Ignite. So I think default-config.xml with all possible parameters would be really useful. > what do you mean "cluster is HA"? High Available cluster. I think if you explain “use IGFS w/o Ignite Map-Reduce, Ignite Map-Reduce w/o IGFS” a little bit more I stop generating silly questions. > This question does not have simple answer: what is done with these data? Suppose this file is Hive table (40 mln records, 30 columns, ORC 500MB, csv 9Gb), and we want to calculate some aggregation (SUM, AVG) group by 3-5 columns. How Ignite will utilize memory for that? > 1 Ignite node per host is okay, if the node can utilize all the host > resources (memory & cpu) How can I find out that ignite node utilizes all the host resources?
