Subject [jira] Updated: (NUTCH-711) Indexer failing after upgrade to Hadoop 0.19.1
Date Wed, 04 Mar 2009 11:07:56 GMT


Andrzej Bialecki  updated NUTCH-711:

    Attachment: patch.txt

This patch instantiates IndexingFilters in IndexerOutputFormat, and thus fixes the issue.
If there are not objections I will commit it shortly.

> After upgrade to Hadoop 0.19.1 Reducer is initialized in a different order than before
(see IndexingFilters populate
current JobConf with field options that are required for IndexerOutputFormat to function properly.
However, the filters are instantiated in Reducer.configure(), which is now called after the
OutputFormat is initialized, and not before as previously.
> The workaround for now is to instantiate IndexinigFilters once again inside IndexerOutputFormat.
 This issue should be revisited before 1.1 in order to find a better solution.
