All- I'm installing Accumulo 1.5 on CDH 4.3. I'm running Hadoop 2.0 (yarn) with High Availability (HA) for the NameNode. When I try to initialize Accumulo I get the following error message:
>sudo -u accumulo accumulo init FATAL: java.lang.IllegalArgumentException: java.net.UnknownHostException: mycluster java.lang.IllegalArgumentException: java.net.UnknownHostException: mycluster at org.apache.hadoop.security.SecurityUtil.buildTokenService(SecurityUtil.java:414) at org.apache.hadoop.hdfs.NameNodeProxies.createNonHAProxy(NameNodeProzies.java:164) at org.apache.hadoop.hdfs.NameNodeProxies.createProxy(NameNodeProxies.java:129) at org.apache.hadoop.hdfs.DFSClient.<init>(DFSClient.java:448) at org.apache.hadoop.hdfs.DFSClient.<init>(DFSClient.java:410) at org.apache.hadoop.hdfs.DistributedFileSystem.initialize(DistributedFileSystem.java:128) at org.apache.hadoop.fs.FileSystem.createFileSystem(FileSystem.java:2308) at org.apache.hadoop.fs.FileSystem.access$200(FileSystem.java:87) at org.apache.hadoop.fs.FileSystem$Cache.getInternal(FileSystem.java:2324) at org.apache.hadoop.fs.FileSystem.get(FileSystem.java:351) at org.apache.hadoop.fs.FileSystem.get(FileSystem.java:163) at org.apache.accumulo.core.file.FileUtil.getFileSystem(FileUtil.java:550) at org.apache.accumulo.server.util.Initialize.main(Initialize.java:485) ... "mycluster" is from my hdfs-site.xml and is part of the HA configuration <property> <name>dfs.nameservices</name> <value>mycluster</value> </property> It's not a hostname and I'm not sure why Accumulo would try to resolve it as if it was a hostname. Any idea why I would get this error or why Accumulo would have trouble running on Hadoop 2.0 with HA? Thanks, Josh
