After you svn up the commit for HIVE-1817 and do ant clean package, you may get errors like the ones below. If so, it means you were relying on the Hadoop 0.20.0 tarball we use for Hive development, and you need to update your $HADOOP_HOME to point to
hive-trunk/build/hadoopcore/hadoop-0.20.1 instead of 0.20.0 Errors: "Cannot find hadoop installation: $HADOOP_HOME must be set or hadoop must be in the path" "Hive requires Hadoop 0.20.x (x >= 1). 'hadoop version' returned: Hadoop 0.20.0 Subversion https://svn.apache.org/repos/asf/hadoop/core/branches/branch-0.20 -r 763504 Compiled by ndaley on Thu Apr 9 05:18:40 UTC 2009" JVS
