Hi, There:
I was trying to compile trunk version of hive with cloudera cdh3b3
distribution and noticed that in
org.apache.hadoop.hive.ql Driver.java was using:
org.apache.hadoop.security.UnixUserGroupInformation;
However, in the cdh3b3 version of hadoop, this class is gone, so Driver.java
doesn't compile.
I checked 0.6 version of hive, the same issue exists.
I noticed that class org.apache.hadoop.security.UserGroupInformation is
still there, both
in cdh3b2 and cdh3b3 version of hadoop. Can we change the Driver.java to use
org.apache.hadoop.security.UserGroupInformation;
instead ? This class does sound like a more generic class that in the
future, we may
even get it to work under windows or other os.
Jimmy.
