Hello, Thanks for answering. Using jmap -heap I got: --------------------------------------------------------- Attaching to process ID 6172, please wait... Debugger attached successfully. Server compiler detected. JVM version is 25.92-b14
using thread-local object allocation. Parallel GC with 10 thread(s) Heap Configuration: MinHeapFreeRatio = 0 MaxHeapFreeRatio = 100 MaxHeapSize = 8430551040 (8040.0MB) NewSize = 176160768 (168.0MB) MaxNewSize = 2810183680 (2680.0MB) OldSize = 352321536 (336.0MB) NewRatio = 2 SurvivorRatio = 8 MetaspaceSize = 21807104 (20.796875MB) CompressedClassSpaceSize = 1073741824 (1024.0MB) MaxMetaspaceSize = 17592186044415 MB G1HeapRegionSize = 0 (0.0MB) Heap Usage: PS Young Generation Eden Space: capacity = 132120576 (126.0MB) used = 78735736 (75.08824920654297MB) free = 53384840 (50.91175079345703MB) 59.593848576621404% used >From Space: capacity = 22020096 (21.0MB) used = 0 (0.0MB) free = 22020096 (21.0MB) 0.0% used To Space: capacity = 22020096 (21.0MB) used = 0 (0.0MB) free = 22020096 (21.0MB) 0.0% used PS Old Generation capacity = 352321536 (336.0MB) used = 0 (0.0MB) free = 352321536 (336.0MB) 0.0% used 5025 interned Strings occupying 406840 bytes. ______________________________ Wich means that max heap size is 8040.0MB. So it did not work. Maybe there is something wrong in my files or at the init step. 1) First I started the CC on the "compute-0-34" machine -> bin/hyrackscc -config-file ~/conf/c034.conf Where c034.conf file is: ============================= [cc] address = compute-0-34 app.class = org.apache.hyracks.control.cc.BaseCCApplication [nc/c036] address = compute-0-36 jvm.args = -Xmx16384m ============================= 2 )Then I started the NC on the "compute-0-36" machine ->bin/hyrackscc -config-file ~/conf/c036.conf Where c036.conf file is: ============================= [nc] address = compute-0-36 cluster.address = compute-0-34 cluster.port = 1099 jvm.args = -Xmx16384m [localnc] node.id = c036 ============================= Is there something I missed? Thanks!
