Mukul Kumar Singh commented on HDDS-3894: ----------------------------------------- cc [~avijayan] > Noisy log at OM when the requested sequence is not written into DB > ------------------------------------------------------------------ > > Key: HDDS-3894 > URL: https://issues.apache.org/jira/browse/HDDS-3894 > Project: Hadoop Distributed Data Store > Issue Type: Bug > Components: Ozone Manager > Reporter: Rakesh Radhakrishnan > Assignee: Rakesh Radhakrishnan > Priority: Minor > > Too many logs at OM, which is noisy. It looks like Recon is making this call > to OM to update the delta info. OM can ignore this exception and reduce the > log priority to DEBUG or so. > *Ozone-om.log* > {code:java} > 2020-06-26 10:02:52,963 INFO > org.apache.ratis.server.raftlog.segmented.SegmentedRaftLogWorker: > 5dca58f5-6231-4858-9589-4e64b1435aa4@group-C5BA1605619E-SegmentedRaftLogWorker: > Rolled log segment from > /data/3/jun27_new1/hadoop-ozone/om/ratis2/bf265839-605b-3f16-9796-c5ba1605619e/current/log_inprogress_106536 > to > /data/3/jun27_new1/hadoop-ozone/om/ratis2/bf265839-605b-3f16-9796-c5ba1605619e/current/log_106536-106603 > 2020-06-26 10:02:52,982 INFO > org.apache.ratis.server.raftlog.segmented.SegmentedRaftLogWorker: > 5dca58f5-6231-4858-9589-4e64b1435aa4@group-C5BA1605619E-SegmentedRaftLogWorker: > created new log segment > /data/3/jun27_new1/hadoop-ozone/om/ratis2/bf265839-605b-3f16-9796-c5ba1605619e/current/log_inprogress_106604 > 2020-06-26 10:09:54,828 ERROR org.apache.hadoop.hdds.utils.db.RDBStore: > Unable to get delta updates since sequenceNumber 11268864 > org.rocksdb.RocksDBException: Requested sequence not yet written in the db > at org.rocksdb.RocksDB.getUpdatesSince(Native Method) > at org.rocksdb.RocksDB.getUpdatesSince(RocksDB.java:3588) > at > org.apache.hadoop.hdds.utils.db.RDBStore.getUpdatesSince(RDBStore.java:339) > at > org.apache.hadoop.ozone.om.OzoneManager.getDBUpdates(OzoneManager.java:3422) > at > org.apache.hadoop.ozone.protocolPB.OzoneManagerRequestHandler.getOMDBUpdates(OzoneManagerRequestHandler.java:257) > at > org.apache.hadoop.ozone.protocolPB.OzoneManagerRequestHandler.handleReadRequest(OzoneManagerRequestHandler.java:194) > at > org.apache.hadoop.ozone.protocolPB.OzoneManagerProtocolServerSideTranslatorPB.submitReadRequestToOM(OzoneManagerProtocolServerSideTranslatorPB.java:171) > at > org.apache.hadoop.ozone.protocolPB.OzoneManagerProtocolServerSideTranslatorPB.processRequest(OzoneManagerProtocolServerSideTranslatorPB.java:109) > at > org.apache.hadoop.hdds.server.OzoneProtocolMessageDispatcher.processRequest(OzoneProtocolMessageDispatcher.java:74) > at > org.apache.hadoop.ozone.protocolPB.OzoneManagerProtocolServerSideTranslatorPB.submitRequest(OzoneManagerProtocolServerSideTranslatorPB.java:99) > at > org.apache.hadoop.ozone.protocol.proto.OzoneManagerProtocolProtos$OzoneManagerService$2.callBlockingMethod(OzoneManagerProtocolProtos.java) > at > org.apache.hadoop.ipc.ProtobufRpcEngine$Server$ProtoBufRpcInvoker.call(ProtobufRpcEngine.java:528) > at org.apache.hadoop.ipc.RPC$Server.call(RPC.java:1070) > at org.apache.hadoop.ipc.Server$RpcCall.run(Server.java:985) > at org.apache.hadoop.ipc.Server$RpcCall.run(Server.java:913) > at java.security.AccessController.doPrivileged(Native Method) > at javax.security.auth.Subject.doAs(Subject.java:422) > at > org.apache.hadoop.security.UserGroupInformation.doAs(UserGroupInformation.java:1876) > at org.apache.hadoop.ipc.Server$Handler.run(Server.java:2882) > 2020-06-26 10:11:08,442 INFO > org.apache.ratis.server.raftlog.segmented.SegmentedRaftLogWorker: > 5dca58f5-6231-4858-9589-4e64b1435aa4@group-C5BA1605619E-SegmentedRaftLogWorker: > Rolling segment log-106604_106637 to index:106637 > 2020-06-26 10:11:08,443 INFO > org.apache.ratis.server.raftlog.segmented.SegmentedRaftLogWorker: > 5dca58f5-6231-4858-9589-4e64b1435aa4@group-C5BA1605619E-SegmentedRaftLogWorker: > Rolling segment log-106638_106654 to index:106654 > 2020-06-26 10:11:08,444 INFO > org.apache.ratis.server.raftlog.segmented.SegmentedRaftLogWorker: > 5dca58f5-6231-4858-9589-4e64b1435aa4@group-C5BA1605619E-SegmentedRaftLogWorker: > Rolling segment log-106655_106671 to index:106671 > {code} > *Recon.log* > {code:java} > 2020-06-26 10:08:55,883 INFO > org.apache.hadoop.ozone.recon.fsck.MissingContainerTask: Missing Container > task Thread took 88 milliseconds for processing 0 containers. > 2020-06-26 10:09:54,824 INFO > org.apache.hadoop.ozone.recon.spi.impl.OzoneManagerServiceProviderImpl: > Syncing data from Ozone Manager. > 2020-06-26 10:09:54,824 INFO > org.apache.hadoop.ozone.recon.spi.impl.OzoneManagerServiceProviderImpl: > Obtaining delta updates from Ozone Manager > 2020-06-26 10:09:54,828 INFO > org.apache.hadoop.ozone.recon.spi.impl.OzoneManagerServiceProviderImpl: > Number of updates received from OM : 0 > {code} -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: ozone-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: ozone-issues-h...@hadoop.apache.org
