Hello!
I've recently installed Accumulo 1.6 on a 3 node cluster and have the processes started and configured correctly to my knowledge, but I am having difficulty running the wordCount example. Specifically, when I run: `./bin/accumulo org.apache.accumulo.examples.simple.mapreduce.WordCount -i accumulo -z zookeeper0:2181 --input /user/jenkins/README -t wordCount -u root -p root --debug` I get the following Thrift error which appears to be from a failure to communicate with my Zookeeper server: https://gist.github.com/davidsnyder/b33fad7b92bc6a906809 Despite the fact that I can run ListInstances just fine with the same "-z" zookeeper arg: [user@hdp0 accumulo]$ ./bin/accumulo org.apache.accumulo.server.util.ListInstances -z zookeeper0:2181 INFO : Using ZooKeepers zookeeper0:2181 Instance Name | Instance ID | Master ---------------------+--------------------------------------+------------------------------- "accumulo" | 4505350e-1f07-48f0-902b-509722e968f5 | I also passed the public ip of the zookeeper instance instead of the DNS, but I also verified that the DNS was resolving: [user@hdp0 accumulo]$ host zookeeper0 zookeeper0.XXX.XXX has address 10.0.1.18 [user@hdp0 accumulo]$ echo ruok | nc zookeeper0 2181 imok[user@hdp0 accumulo]$ I can create tables in the shell, insert records, scan, everything just fine. The monitor GUI shows my two tablet servers and there are no other errors to speak of. I also attempted to use the helloworld "org.apache.accumulo.examples.simple.helloworld.InsertWithBatchWriter" jar and received the same result as I did with WordCount. There's nothing to speak of in the accumulo logs. The zookeeper logs repeatedly show the following when I run the wordCount command line (10.0.0.1 is the internal ip of hdp0): 014-07-23 22:57:50,670 [myid:] - INFO [Thread-3079:NIOServerCnxn@1001] - Closed socket connection for client /10.0.0.101:44342 (no session established for client) 2014-07-23 22:57:55,671 [myid:] - INFO [NIOServerCxn.Factory: 0.0.0.0/0.0.0.0:2181:NIOServerCnxnFactory@197] - Accepted socket connection from /10.0.0.101:44363 2014-07-23 22:57:55,671 [myid:] - INFO [NIOServerCxn.Factory: 0.0.0.0/0.0.0.0:2181:NIOServerCnxn@821] - Processing stat command from / 10.0.0.101:44363 2014-07-23 22:57:55,672 [myid:] - INFO [Thread-3081:NIOServerCnxn@1001] - Closed socket connection for client /10.0.0.101:44363 (no session established for client) 2014-07-23 22:58:00,673 [myid:] - INFO [NIOServerCxn.Factory: 0.0.0.0/0.0.0.0:2181:NIOServerCnxnFactory@197] - Accepted socket connection from /10.0.0.101:44380 2014-07-23 22:58:00,677 [myid:] - INFO [NIOServerCxn.Factory: 0.0.0.0/0.0.0.0:2181:NIOServerCnxn@821] - Processing stat command from / 10.0.0.101:44380 2014-07-23 22:58:00,678 [myid:] - INFO [Thread-3083:NIOServerCnxn@1001] - Closed socket connection for client /10.0.0.101:44380 (no session established for client) I'm really not sure what else to try at this point. Any ideas? Thanks, David Snyder
