Hi Folks,   I have a problem starting a node manager (actually two) the third is starting without any problem.   The failing node manager has this fatal error : Error starting NodeManager java.lang.UnsatisfiedLinkError: Could not load library. Reasons: [no leveldbjni64-1.8 in java.library.path, no leveldbjni-1.8 in java.library.path, no leveldbjni in java.library.path, /tmp/libleveldbjni-64-1-1006449310407885041.8: /tmp/libleveldbjni-64-1-1006449310407885041.8: failed to map segment from shared object: Operation not permitted] at org.fusesource.hawtjni.runtime.Library.doLoad(Library.java:182) at org.fusesource.hawtjni.runtime.Library.load(Library.java:140) at org.fusesource.leveldbjni.JniDBFactory.<clinit>(JniDBFactory.java:48) at org.apache.hadoop.yarn.server.nodemanager.recovery.NMLeveldbStateStoreService.initStorage(NMLeveldbStateStoreService.java:864) at org.apache.hadoop.yarn.server.nodemanager.recovery.NMStateStoreService.serviceInit(NMStateStoreService.java:195) at org.apache.hadoop.service.AbstractService.init(AbstractService.java:163) at org.apache.hadoop.yarn.server.nodemanager.NodeManager.initAndStartRecoveryStore(NodeManager.java:155) at org.apache.hadoop.yarn.server.nodemanager.NodeManager.serviceInit(NodeManager.java:193) at org.apache.hadoop.service.AbstractService.init(AbstractService.java:163) at org.apache.hadoop.yarn.server.nodemanager.NodeManager.initAndStartNodeManager(NodeManager.java:462) at org.apache.hadoop.yarn.server.nodemanager.NodeManager.main(NodeManager.java:509)   We're using parcels and tried to verify permissions but dont see any problem. Even the process run from the agent is detecting the right version and path for the parcel. The host inspector is not reporting anuy problem.   Any help will be more than appreciated.   Best regards, Mehdi ... View more
