Hi Adina, After a restart I used *accumulo-1.6.4/bin/stop-all.sh* and after that I start accumulo again with *accumulo-1.6.4/bin/start-all.sh * then I can successfully start accumulo without initializing problem.
But after I changed the Datadir value to a local, I can successfully start Zookeeper. Then I tried to start accumulo using *accumulo-1.6.4/bin/start-all.sh *but I got the following, amila@amila-X550LD:~$ ~/Installs/accumulo-1.6.4/bin/start-all.sh Starting monitor on localhost WARN : Max open files on localhost is 1024, recommend 32768 Starting tablet servers .... done 2016-05-14 16:34:54,379 [server.Accumulo] INFO : Attempting to talk to zookeeper Starting tablet server on localhost WARN : Max open files on localhost is 1024, recommend 32768 Thread "org.apache.accumulo.master.state.SetGoalState" died Failed to connect to zookeeper (localhost:2181) within 2x zookeeper timeout period 30000 java.lang.RuntimeException: Failed to connect to zookeeper (localhost:2181) within 2x zookeeper timeout period 30000 at org.apache.accumulo.fate.zookeeper.ZooSession.connect(ZooSession.java:123) at org.apache.accumulo.fate.zookeeper.ZooSession.getSession(ZooSession.java:167) at org.apache.accumulo.fate.zookeeper.ZooReader.getSession(ZooReader.java:39) at org.apache.accumulo.fate.zookeeper.ZooReaderWriter.getZooKeeper(ZooReaderWriter.java:50) at org.apache.accumulo.fate.zookeeper.ZooReader.getChildren(ZooReader.java:128) at org.apache.accumulo.server.Accumulo.waitForZookeeperAndHdfs(Accumulo.java:269) at org.apache.accumulo.master.state.SetGoalState.main(SetGoalState.java:46) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:606) at org.apache.accumulo.start.Main$1.run(Main.java:141) at java.lang.Thread.run(Thread.java:745) Starting master on localhost WARN : Max open files on localhost is 1024, recommend 32768 Starting garbage collector on localhost WARN : Max open files on localhost is 1024, recommend 32768 Starting tracer on localhost WARN : Max open files on localhost is 1024, recommend 32768 Any idea about this is appreciated.
