Hi, I have a 3 node HBase cluster up and running. I could list and scan tables in HBase shell. I am trying to run HBase map-reduce job to load bulk data from TSV file. It fails with
12/07/04 11:42:11 INFO mapred.JobClient: Task Id : attempt_201207031124_0022_m_000002_0, Status : FAILED java.lang.RuntimeException: java.net.UnknownHostException: unknown host: honeywel-4a7632 I had same issue when I ran HBase client API code from my laptop. I added this hostname in my hosts file. Then I could run client code and retrieve data. Still importtsv map reduce job alone fails. I added an entry for this hostname in /etc/hosts file. I even tried removing all host names from my Hbase and Hadoop cluster configuration files. Then I tried hadoop dfsadmin -refreshNodes. Any idea, why this map-reduce job alone fails? Please let me know if you seen this same error. -- Regards, Anand
