Hi Prashant, Could you please collect more logs, please add "-DIGNITE_QUIET=false" arg to Createcache and TestMapper runs?
I even tried CentOS with the same version as you have, but it still works fine for me. I have a suggestion, usually there's separate account for Hadoop, and when you try to run Ignite from hadoop mapper it runs it under hadoop's account, so may this some doesn't allow TestMapper to see CreateCache. I didn't check this suggestion, but you may be try to run hadoop and CreateCache under the same account. Thanks, Mikhail. 2017-06-07 7:37 GMT+03:00 Prashant312 <[email protected]>: > Hi, > > Please see the linux version.. > > [p_hadoop@HMCISPRDATAWARE ~]$ uname -a > Linux HMCISPRDATAWARE 2.6.32-431.el6.x86_64 #1 SMP Fri Nov 22 03:15:09 UTC > 2013 x86_64 x86_64 x86_64 GNU/Linux > [p_hadoop@HMCISPRDATAWARE ~]$ cat /etc/redhat-release > CentOS release 6.5 (Final) > [p_hadoop@HMCISPRDATAWARE ~]$ lsb_release -a > LSB Version: > :base-4.0-amd64:base-4.0-noarch:core-4.0-amd64:core-4. > 0-noarch:graphics-4.0-amd64:graphics-4.0-noarch:printing- > 4.0-amd64:printing-4.0-noarch > Distributor ID: CentOS > Description: CentOS release 6.5 (Final) > Release: 6.5 > Codename: Final > [p_hadoop@HMCISPRDATAWARE ~]$ cat /proc/version > Linux version 2.6.32-431.el6.x86_64 ([email protected]) > (gcc version 4.4.7 20120313 (Red Hat 4.4.7-4) (GCC) ) #1 SMP Fri Nov 22 > 03:15:09 UTC 2013 > [p_hadoop@HMCISPRDATAWARE ~]$ cat /etc/issue > CentOS release 6.5 (Final) > Kernel \r on an \m > > [p_hadoop@HMCISPRDATAWARE ~]$ > > ------------------------------------------------------------------------ > > Below is the log for createcache class... > > [p_hadoop@HMCISPRDATAWARE ~]$ tail -100f > /home/p_hadoop/pravin/igniteCache.log > Jun 07, 2017 3:35:04 PM java.util.logging.LogManager$RootLogger log > SEVERE: Failed to resolve default logging config file: > config/java.util.logging.properties > [15:35:04] __________ ________________ > [15:35:04] / _/ ___/ |/ / _/_ __/ __/ > [15:35:04] _/ // (7 7 // / / / / _/ > [15:35:04] /___/\___/_/|_/___/ /_/ /___/ > [15:35:04] > [15:35:04] ver. 2.0.0#20170430-sha1:d4eef3c6 > [15:35:04] 2017 Copyright(C) Apache Software Foundation > [15:35:04] > [15:35:04] Ignite documentation: http://ignite.apache.org > [15:35:04] > [15:35:04] Quiet mode. > [15:35:04] ^-- To see **FULL** console log here add -DIGNITE_QUIET=false > or "-v" to ignite.{sh|bat} > [15:35:04] > [15:35:04] OS: Linux 2.6.32-431.el6.x86_64 amd64 > [15:35:04] VM information: Java(TM) SE Runtime Environment 1.8.0_121-b13 > Oracle Corporation Java HotSpot(TM) 64-Bit Server VM 25.121-b13 > [15:35:04] Configured plugins: > [15:35:04] ^-- None > [15:35:04] > [15:35:04] Message queue limit is set to 0 which may lead to potential > OOMEs > when running cache operations in FULL_ASYNC or PRIMARY_SYNC modes due to > message queues growth on sender and receiver sides. > [15:35:04] Security status [authentication=off, tls/ssl=off] > [15:35:04] Performance suggestions for grid (fix if possible) > [15:35:04] To disable, set -DIGNITE_PERFORMANCE_SUGGESTIONS_DISABLED=true > [15:35:04] ^-- Enable G1 Garbage Collector (add '-XX:+UseG1GC' to JVM > options) > [15:35:04] ^-- Set max direct memory size if getting 'OOME: Direct buffer > memory' (add '-XX:MaxDirectMemorySize=<size>[g|G|m|M|k|K]' to JVM options) > [15:35:04] ^-- Disable processing of calls to System.gc() (add > '-XX:+DisableExplicitGC' to JVM options) > [15:35:04] ^-- Speed up flushing of dirty pages by OS (alter > vm.dirty_expire_centisecs parameter by setting to 500) > [15:35:04] ^-- Reduce pages swapping ratio (set vm.swappiness=10) > [15:35:04] ^-- Disable NUMA memory reclaim (set vm.zone_reclaim_mode=0) > [15:35:04] ^-- Avoid direct reclaim and page allocation failures (set > vm.extra_free_kbytes=1240000) > [15:35:04] Refer to this page for more performance suggestions: > https://apacheignite.readme.io/docs/jvm-and-system-tuning > [15:35:04] > [15:35:04] To start Console Management & Monitoring run > ignitevisorcmd.{sh|bat} > [15:35:04] > [15:35:04] Ignite node started OK (id=b9c64c6d) > [15:35:04] Topology snapshot [ver=1, servers=1, clients=0, CPUs=24, > heap=22.0GB] > Done....cache > > Thanks, > Prashant > > > > -- > View this message in context: http://apache-ignite-users. > 70518.x6.nabble.com/Ignite-Cache-returning-Null-value- > from-Mapper-tp13158p13448.html > Sent from the Apache Ignite Users mailing list archive at Nabble.com. >
