Subject [jira] [Commented] (HIVE-2757) hive can't find hadoop executor scripts without HADOOP_HOME set
Date Wed, 25 Apr 2012 20:28:18 GMT


Carl Steinbach commented on HIVE-2757:

@Ed: o.a.h.Configuration is responsible for locating the Hadoop configuration files on the
classpath at time of initialization. Since HiveConf extends Configuration we inherit this
functionality for free. I agree that it may eventually become necessary to dynamically modify
the classpath at runtime to include the Hadoop conf directory, but right now we don't do that,
and in the meantime ConfVars.HADOOPCONF is dead code (which is really confusing, since developers
always assume that the code they read is used somewhere).

> The trouble is that in Hadoop 0.23 HADOOP_HOME has been deprecated. I think it would
be really nice if bin/hive can be modified to capture the which hadoop
