> > OM is not yet compatible with ratis 3.1.0. such as [RATIS-2011](https://issues.apache.org/jira/browse/RATIS-2011). ... > > @whbing , [RATIS-2011](https://issues.apache.org/jira/browse/RATIS-2011) was to fix a memory leak issue (otherwise, some TransactionContext objects will not be removed from the map.) Why it courses the failure? 1. OM build failed with ratis 3.1.0 because it calls `RatisHelper.attemptUntilTrue` which removed in RATIS-2011. 2. OM also start failed with the new `ratis-common-.jar`, with err: ```java java.lang.NoClassDefFoundError: Could not initialize class org.apache.ratis.protocol.RaftClientRequest at org.apache.hadoop.ozone.om.ratis.OzoneManagerRatisServer.createRaftRequestImpl(OzoneManagerRatisServer.java:458) at org.apache.hadoop.ozone.om.ratis.OzoneManagerRatisServer.lambda$3(OzoneManagerRatisServer.java:296) at org.apache.hadoop.util.MetricUtil.captureLatencyNs(MetricUtil.java:45) at org.apache.hadoop.ozone.om.ratis.OzoneManagerRatisServer.createRaftRequest(OzoneManagerRatisServer.java:294) at org.apache.hadoop.ozone.om.ratis.OzoneManagerRatisServer.submitRequest(OzoneManagerRatisServer.java:259) at org.apache.hadoop.ozone.protocolPB.OzoneManagerProtocolServerSideTranslatorPB.submitReadRequestToRatis(OzoneManagerProtocolServerSideTranslatorPB.java:264) at org.apache.hadoop.ozone.protocolPB.OzoneManagerProtocolServerSideTranslatorPB.submitReadRequestToOM(OzoneManagerProtocolServerSideTranslatorPB.java:271) at org.apache.hadoop.ozone.protocolPB.OzoneManagerProtocolServerSideTranslatorPB.internalProcessRequest(OzoneManagerProtocolServerSideTranslatorPB.java:211) at org.apache.hadoop.ozone.protocolPB.OzoneManagerProtocolServerSideTranslatorPB.processRequest(OzoneManagerProtocolServerSideTranslatorPB.java:171) at org.apache.hadoop.hdds.server.OzoneProtocolMessageDispatcher.processRequest(OzoneProtocolMessageDispatcher.java:89) at org.apache.hadoop.ozone.protocolPB.OzoneManagerProtocolServerSideTranslatorPB.submitRequest(OzoneManagerProtocolServerSideTranslatorPB.java:162) at org.apache.hadoop.ozone.protocol.proto.OzoneManagerProtocolProtos$OzoneManagerService$2.callBlockingMethod(OzoneManagerProtocolProtos.java) at org.apache.hadoop.ipc.ProtobufRpcEngine$Server.processCall(ProtobufRpcEngine.java:484) at org.apache.hadoop.ipc.ProtobufRpcEngine2$Server$ProtoBufRpcInvoker.call(ProtobufRpcEngine2.java:595) at org.apache.hadoop.ipc.ProtobufRpcEngine2$Server$ProtoBufRpcInvoker.call(ProtobufRpcEngine2.java:573) at org.apache.hadoop.ipc.RPC$Server.call(RPC.java:1227) at org.apache.hadoop.ipc.Server$RpcCall.run(Server.java:1098) at org.apache.hadoop.ipc.Server$RpcCall.run(Server.java:1021) at java.security.AccessController.doPrivileged(Native Method) at javax.security.auth.Subject.doAs(Subject.java:422) at org.apache.hadoop.security.UserGroupInformation.doAs(UserGroupInformation.java:1953) at org.apache.hadoop.ipc.Server$Handler.run(Server.java:3060) ``` I've done some tests just based on ratis-common-3.0.1.jar and updated in the above doc. -- This is an automated message from the Apache Git Service.
