Hi, It's been awhile since I've been working with Accumulo. To recap I have a standalone system with Hadoop, Zookeeper, and Accumulo 1.8.1 on it.
When I tried to start the Accumulo, it kept looping and indicating "waiting for initialization". So I was doing some googling and found that the dataDir in the zoo.cfg was set to /tmp. Luckily (I think) i have a snapshot of this system, so I restored from my last snapshot and it seems to be running all right now, but I want to fix that dataDir parameter, so I created a new directory, /apps/Zookeeper-data, and chmod'ed it to 777, but then, when I try to start Accumulo it just kind of hangs. I saw from another place that I should run the "accumulo init" so I did that, and now, when I do start-all.sh, it seems like Accumulo is starting, but I cannot get to the Accumulo shell (it starts part wa, then seems to hang, a few lines after I enter the password: 2017-07-29 19:32:49,167 [hdfs.BlockReaderLocal] DEBUG: dfs.client.domain.socket.data.traffic = false 2017-07-29 19:32:49,167 [hdfs.BlockReaderLocal] DEBUG: dfs.domain.socket.path = 2017-07-29 19:32:49,267 [retry.RetryUtils] DEBUG: multipleLinearRandomRetry = null 2017-07-29 19:32:49,306 [ipc.Server] DEBUG: rpcKind=RPC_PROTOCOL_BUFFER, rpcRequestWrapperClass=class org.apache.hadoop.ipc.ProtobufRpcEngine$RpcRequestWrapper, rpcInvoker=org.apache.hadoop.ipc.ProtobufRpcEngine$Server$ProtoBufRpcInvoker@15a13207 2017-07-29 19:32:49,319 [ipc.Client] DEBUG: getting client out of cache: org.apache.hadoop.ipc.Client@51de4e31 2017-07-29 19:32:49,767 [unix.DomainSocketWatcher] DEBUG: org.apache.hadoop.net.unix.DomainSocketWatcher$2@16577601: starting with interruptCheckPeriodMs = 60000 2017-07-29 19:32:49,772 [util.PerformanceAdvisory] DEBUG: Both short-circuit local reads and UNIX domain socket are disabled. 2017-07-29 19:32:49,778 [sasl.DataTransferSaslUtil] DEBUG: DataTransferProtocol not using SaslPropertiesResolver, no QOP found in configuration for dfs.data.transfer.protection 2017-07-29 19:32:49,824 [ipc.Client] DEBUG: The ping interval is 60000 ms. 2017-07-29 19:32:49,826 [ipc.Client] DEBUG: Connecting to localhost/127.0.0.1:9000 2017-07-29 19:32:49,850 [ipc.Client] DEBUG: IPC Client (958411794) connection to localhost/127.0.0.1:9000 from oracle: starting, having connections 1 2017-07-29 19:32:49,861 [ipc.Client] DEBUG: IPC Client (958411794) connection to localhost/127.0.0.1:9000 from oracle sending #0 2017-07-29 19:32:49,870 [ipc.Client] DEBUG: IPC Client (958411794) connection to localhost/127.0.0.1:9000 from oracle got value #0 2017-07-29 19:32:49,870 [ipc.ProtobufRpcEngine] DEBUG: Call: getListing took 61ms Password: ****** 2017-07-29 19:32:54,605 [zookeeper.ZooSession] DEBUG: Connecting to localhost:2181 with timeout 30000 with auth 2017-07-29 19:32:54,814 [tracer.ZooTraceClient] DEBUG: Successfully initialized tracer hosts from ZooKeeper 2017-07-29 19:32:54,815 [trace.DistributedTrace] INFO : SpanReceiver org.apache.accumulo.tracer.ZooTraceClient was loaded successfully. 2017-07-29 19:32:54,843 [impl.ServerClient] WARN : There are no tablet servers: check that zookeeper and accumulo are running. 2017-07-29 19:32:59,851 [ipc.Client] DEBUG: IPC Client (958411794) connection to localhost/127.0.0.1:9000 from oracle: closed 2017-07-29 19:32:59,851 [ipc.Client] DEBUG: IPC Client (958411794) connection to localhost/127.0.0.1:9000 from oracle: stopped, remaining connections 0 I can go back to the snapshot that has the dataDir pointing to /tmp, but can someone tell me the steps that I would need to get the system running after I change dataDir?
