Hi. This is my first time setting up accumulo. So I'm starting with a single node "cluster" on Ubuntu 13.04. My setup is...
hadoop 1.2.0 (prebuilt tarball from Apache) -- The version will turn out to be important! zookeeper 3.4.5 (prebuilt tarball from Apache) accumulo 1.5.0 (custom build, to target hadoop 1.2) As I understand, because I am running hadoop 1.2, I need to do a custom build. So I did, following the README for Accumulo. So I fire up hadoop, then zookeeper and then accumulo. Looks good so far: $ jps 21231 SecondaryNameNode 20733 NameNode 24274 Jps 22556 Main 21994 Main 20978 DataNode 22306 Main 21764 QuorumPeerMain 21570 TaskTracker 22409 Main 21322 JobTracker Then I try to fire up an accumulo shell (still following the README) and I am told that there are no tablet servers! Here is what I get in /usr/local/accumulo/logs/tracer_mybox.log: 2013-08-03 18:32:44,918 [impl.ServerClient] WARN : There are no tablet servers: check that zookeeper and accumulo are running. I check jps, and everything is still running. And here is what I have in /usr/local/accumulo/logs/tserver_mybox.log: 2013-08-03 18:32:41,292 [tabletserver.TabletServer] FATAL: Must set dfs.durable.sync OR dfs.support.append to true. Which one needs to be set depends on your version of HDFS. See ACCUMULO-623. HADOOP RELEASE VERSION SYNC NAME DEFAULT Apache Hadoop 0.20.205 dfs.support.append false Apache Hadoop 0.23.x dfs.support.append true Apache Hadoop 1.0.x dfs.support.append false Apache Hadoop 1.1.x dfs.durable.sync true Apache Hadoop 2.0.0-2.0.2 dfs.support.append true Cloudera CDH 3u0-3u3 ???? true Cloudera CDH 3u4 dfs.support.append true Hortonworks HDP `1.0 dfs.support.append false Hortonworks HDP `1.1 dfs.support.append false And, yes, I remember seeing that in the README. But now you see my problem. Hadoop 1.2 is not on the list! At least, I assume that's my only problem. :) Can someone please tell me which of the two dfs options I need? Thanks very much! Carlos
