Hi Jeffrey, It's strange that you were able to get the other services started but not the master. Is your accumulo-env.sh file set up correctly? What version of Hadoop are you using? Hadoop 3 is required for Accumulo 2.0. It looks like you initialized your Accumulo instance (using 'accumulo init') but you should check that a file named after your instance ID is printed when you run the command below:
hadoop fs -ls hdfs://localhost:9000/accumulo/instance_id/ It looks like you are running Accumulo locally. You might want to try using uno: https://github.com/apache/fluo-uno -Mike On Thu, Dec 13, 2018 at 9:30 AM Jeffrey Zeiberg <jzeib...@gmail.com> wrote: > I know that NameNode and DataNode are running and I know I have a file > system from this: > > [jzeiberg@sr-linux2 conf]$ hadoop fs -ls hdfs://localhost:9000/ > Found 4 items > -rw-rw-rw- 1 hdfs supergroup 0 2018-12-05 10:57 > hdfs://localhost:9000/MY_HADOOP_CLUSTER > drwx------ - jzeiberg supergroup 0 2018-12-12 13:54 > hdfs://localhost:9000/accumulo > drwxr-xr-x - jzeiberg supergroup 0 2018-12-05 14:14 > hdfs://localhost:9000/failures > drwxr-xr-x - jzeiberg supergroup 0 2018-12-05 14:14 > hdfs://localhost:9000/import > > > But when I run either of these commands: > accumulo-service master start > or > accumulo-cluster restart > > > I get this error for the master service (the others start fine): > > 018-12-12 13:28:33,449 [conf.SiteConfiguration] INFO : Found Accumulo > configuration on classpath at > /home/jzeiberg/accumulo/accumulo-2.0.0-SNAPSHOT/conf/accumulo.properties > 2018-12-12 13:28:33,643 [zookeeper.ZooUtil] ERROR: Problem reading instance > id out of hdfs at hdfs://localhost:9000/accumulo/instance_id > java.io.IOException: No FileSystem for scheme: hdfs > at > org.apache.hadoop.fs.FileSystem.getFileSystemClass(FileSystem.java:2796) > at > org.apache.hadoop.fs.FileSystem.createFileSystem(FileSystem.java:2810) > at org.apache.hadoop.fs.FileSystem.access$200(FileSystem.java:98) > at > org.apache.hadoop.fs.FileSystem$Cache.getInternal(FileSystem.java:2853) > at org.apache.hadoop.fs.FileSystem$Cache.get(FileSystem.java:2835) > at org.apache.hadoop.fs.FileSystem.get(FileSystem.java:387) > at org.apache.hadoop.fs.Path.getFileSystem(Path.java:296) > at > org.apache.accumulo.core.volume.VolumeImpl.<init>(VolumeImpl.java:45) > at > > org.apache.accumulo.core.volume.VolumeConfiguration.create(VolumeConfiguration.java:161) > at > > org.apache.accumulo.core.volume.VolumeConfiguration.getVolume(VolumeConfiguration.java:40) > at > > org.apache.accumulo.fate.zookeeper.ZooUtil.getInstanceIDFromHdfs(ZooUtil.java:591) > at > > org.apache.accumulo.fate.zookeeper.ZooUtil.getInstanceIDFromHdfs(ZooUtil.java:585) > at org.apache.accumulo.server.util.ZooZap.main(ZooZap.java:76) > at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) > at > > sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) > at > > sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) > at java.lang.reflect.Method.invoke(Method.java:498) > at > org.apache.accumulo.start.Main.lambda$execMainClass$1(Main.java:166) > at java.lang.Thread.run(Thread.java:748) > 2018-12-12 13:28:33,644 [start.Main] ERROR: Thread > 'org.apache.accumulo.server.util.ZooZap' died. > java.lang.RuntimeException: Can't tell if Accumulo is initialized; can't > read instance id at hdfs://localhost:9000/accumulo/instance_id > at > > org.apache.accumulo.fate.zookeeper.ZooUtil.getInstanceIDFromHdfs(ZooUtil.java:613) > at > > org.apache.accumulo.fate.zookeeper.ZooUtil.getInstanceIDFromHdfs(ZooUtil.java:585) > at org.apache.accumulo.server.util.ZooZap.main(ZooZap.java:76) > at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) > at > > sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) > at > > sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) > at java.lang.reflect.Method.invoke(Method.java:498) > at > org.apache.accumulo.start.Main.lambda$execMainClass$1(Main.java:166) > at java.lang.Thread.run(Thread.java:748) > Caused by: java.io.IOException: No FileSystem for scheme: hdfs > at > org.apache.hadoop.fs.FileSystem.getFileSystemClass(FileSystem.java:2796) > at > org.apache.hadoop.fs.FileSystem.createFileSystem(FileSystem.java:2810) > at org.apache.hadoop.fs.FileSystem.access$200(FileSystem.java:98) > at > org.apache.hadoop.fs.FileSystem$Cache.getInternal(FileSystem.java:2853) > at org.apache.hadoop.fs.FileSystem$Cache.get(FileSystem.java:2835) > at org.apache.hadoop.fs.FileSystem.get(FileSystem.java:387) > at org.apache.hadoop.fs.Path.getFileSystem(Path.java:296) > at > org.apache.accumulo.core.volume.VolumeImpl.<init>(VolumeImpl.java:45) > at > > org.apache.accumulo.core.volume.VolumeConfiguration.create(VolumeConfiguration.java:161) > at > > org.apache.accumulo.core.volume.VolumeConfiguration.getVolume(VolumeConfiguration.java:40) > at > > org.apache.accumulo.fate.zookeeper.ZooUtil.getInstanceIDFromHdfs(ZooUtil.java:591) > > > > > -- > Sent from: http://apache-accumulo.1065345.n5.nabble.com/Developers-f3.html >
