Hey Koert, I am assuming 'thrift' is the name of user through which thrift metastore is running. I also assume you are running in unsecure mode. If you run with security turned on, meaning secure hadoop cluster with secure thrift server, you will see the name of the original user. This is so because in secure mode, metastore server proxies the original user through doAs() which preserves the identity which is not the case in unsecure mode. Through hive client you see the usernames correctly even In unsecure mode because its a hive client process (which is run as koert) which does the filesystem operations.
Hope it helps, Ashutosh On Tue, Sep 6, 2011 at 08:22, Koert Kuipers <ko...@tresata.com> wrote: > When i run a query from the hive command line client i can see that it is > being run as me (for example, in HDFS log i see INFO > org.apache.hadoop.hdfs.server.namenode.FSNamesystem.audit: ugi=koert). > > But when i do anything with the thrift interface my username is lost (i see > ugi=thrift in HDFS logs).
