Hi Experts, In RM GUI, the Reserved Memory is too high and there is a instance where it shows 5GB with no applications running. [check image attached]. I ran a wordcount job with 8GB map opts.
hadoop job -list shows reserved memory for 1 container is 273GB. job_1447682088038_32310 RUNNING 1450121135056 cstonedip root.dmeer NORMAL 45 *1* 137216M *279552M* 416768M http://lgpbd1020.gso.aexp.com:8088/proxy/application_1447682088038_32310/ job_1447682088038_32337 RUNNING 1450122255021 meric root.dmeer NORMAL 48 *0* 193536M *0M* 193536M http://lgpbd1020.gso.aexp.com:8088/proxy/application_1447682088038_32337/ job_1447682088038_32312 RUNNING 1450121158634 cstonedip root.dmeer NORMAL 33 *1* 100352M *49152M* 149504M http://lgpbd1020.gso.aexp.com:8088/proxy/application_1447682088038_32312/ job_1447682088038_32311 RUNNING 1450121142496 cstonedip root.dmeer NORMAL 28 *1* 84992M *76800M* 161792M http://lgpbd1020.gso.aexp.com:8088/proxy/application_1447682088038_32311/ job_1447682088038_32349 RUNNING 1450122721560 netqualrptg root.dmeer NORMAL 26 *1* 78848M *141312M* 220160M http://lgpbd1020.gso.aexp.com:8088/proxy/application_1447682088038_32349/ We can see here for one reserved container, the memory reserved is 279552MB ( 273GB). Total reserved memory for 4 containers are *279552M + **49152M + **76800M + * *141312M = 273 + 48 + 75 + 138 = 534 GB* Please help me in figuring out what could be wrong in the cluster or is it a known Bug. Thanks, Prabhu Joseph
