I have installed Accumulo 1.4.2 on top of Hadoop 0.20 and ZooKeeper 3.4.3 on CentOS 2.6.
I can start Hadoop namenode, datanodes, jobtracker, tasktrackers and 3-node zoo ensemble. I can create things in Hadoop hdfs and zookeeper. I did "accumulo init" without problems. I can reach the accumulo web interface at http://x.x.x.x:50095/ which shows both tablet servers up and happy. Log files everywhere are free of exceptions. From "accumulo shell", I typed "createtable foobar". One of the accumulo tabletserver log files shows: 2013-01-14 13:12:46,168 [server.TNonblockingServer] ERROR: Unexpected exception while invoking! java.lang.NumberFormatException: For input string: "b53c3a3610ce0001" at java.lang.NumberFormatException.forInputString(NumberFormatException.java:48) at java.lang.Long.parseLong(Long.java:422) at org.apache.accumulo.core.zookeeper.ZooUtil$LockID.<init>(ZooUtil.java:64) at org.apache.accumulo.server.tabletserver.TabletServer$ThriftClientHandler.checkPermission(TabletServer.java:1794) at org.apache.accumulo.server.tabletserver.TabletServer$ThriftClientHandler.loadTablet(TabletServer.java:1814) at org.apache.accumulo.core.tabletserver.thrift.TabletClientService$Processor.process(TabletClientService.java:2037) at org.apache.accumulo.server.util.TServerUtils$TimedProcessor.process(TServerUtils.java:154) at org.apache.thrift.server.TNonblockingServer$FrameBuffer.invoke(TNonblockingServer.java:631) at org.apache.accumulo.server.util.TServerUtils$THsHaServer$Invocation.run(TServerUtils.java:202) ZooUtil$LockID.<init>() on line 64 is: "eid = Long.parseLong(sa[1], 16);" so it's trying to convert b53c3a3610ce0001 to a long. In a separate test file I did Long.parseLong("b53c3a3610ce0001", 16), which indeed throws NumberFormatException. Long.MAX_LONG is 9223372036854775807, or 7FFFFFFFFFFFFFFF in hex. b53c3a3610ce0001 is larger than this. I can't see where this "serializedLID" parameter in ZooUtil comes from, or why it would be > Long.MAX_LONG. Any ideas how to trace this and find out what is happening? Thanks, - Rich
