Subject [jira] Commented: (HIVE-1359) Unit test should be shim-aware
Date Fri, 28 May 2010 20:08:38 GMT

    [ https://issues.apache.org/jira/browse/HIVE-1359?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12873132#action_12873132

Ning Zhang commented on HIVE-1359:
----------------------------------

@ashish, what you propose is a finer granular control of under which configuration this test
file should be excluded (a test is included to all configurations by default). This is fine
as well. Actually Paul has a txn that implement this already. So we may just take that change
and let user specify that per .q file.

> Some features in Hive only works for certain Hadoop versions through shim. However the
unit test structure is not shim-aware in that there is only one set of queries and expected
outputs for all Hadoop versions. This may not be sufficient when we will have different output
for different Hadoop versions. One example is CombineHiveInputFormat wich is only available
from Hadoop 0.20. The plan using CombineHiveInputFormat and HiveInputFormat may be different.
Another example is archival partitions (HAR) which is also only available from 0.20.
