Hi everyone Continuing on my journey in Hadoop world. I have installed: Hive 0.9 on Hbase 0.94.2 cluster atop an Hadoop 1.0.3 cluster.
When I do simply query like "select *" everything is fine. When I try "select foo from myTestTable" I see the MR start on my hadoop monitor UI and it fails with: Error: java.lang.ClassNotFoundException: com.google.protobuf.Message at java.net.URLClassLoader$1.run at java.net.URLClassLoader$1.run at java.security.AccessController.doPrivileged at java.net.URLClassLoader.findClass at java.lang.ClassLoader.loadClass at sun.misc.Launcher$AppClassLoader.loadClass at java.lang.ClassLoader.loadClass at org.apache.hadoop.hbase.io.HbaseObjectWritable.<clinit at org.apache.hadoop.hbase.ipc.Invocation.write Anyone have this problem: The jar is present in hbase lib directory. I have copied the jar in my hive libs directory with no result.
