Subject [jira] Commented: (PIG-1453) [zebra] Intermittent failure for TestOrderPreserveUnionHDFS
Date Wed, 16 Jun 2010 19:10:23 GMT

    [ https://issues.apache.org/jira/browse/PIG-1453?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12879462#action_12879462

Yan Zhou commented on PIG-1453:

There are two issues that generally make some test cases (not just TestOrderPreserveUnionHDFS)
in Zebra's "pigtest" fail intermittently.

1) There is some randomness when multiple tables are unioned. The correctness check relies
on the ordering of tables in output rows, which is incorrect. Instead the table a particular
row belongs to can only be associated with the table index in output;

2) There are some failures in PIG STORE calls as the destination directory are not cleaned
up properly before store.
