Just a quick information about something in Hive.
If you ever typed:
$ ant clean package test
to run Apache Hive unit tests, you may have seen that Hive sometimes creates two output files.
If you run for example:
$ ant test -Dtestcase=TestCliDriver -Dqfile=alter5.q
Hive sometimes generates a alter5.q.out and a alter5.q.out.orig :
This happens because Hive uses a method to mask any local information, as local time, or local path, with the following sentence:
#### A masked pattern was here ####
So, if you check your .q.out file it should have a bunch of this sentence above covering several local information. This information needs to be covered so that the tests outputs are the same in all computers.
The .q.out.orig file has the original test output, with all the local information non covered.
Out of curiosity, the method to mask the local patterns (private void maskPatterns(String patterns, String fname) throws Exception) is located on:
