Lewis John McGibbney updated NUTCH-1303: ---------------------------------------- Patch Info: Patch Available > Fetcher to skip queues for URLS getting repeated exceptions, based on > percentage > -------------------------------------------------------------------------------- > > Key: NUTCH-1303 > URL: https://issues.apache.org/jira/browse/NUTCH-1303 > Project: Nutch > Issue Type: Improvement > Components: fetcher > Affects Versions: 1.4 > Reporter: behnam nikbakht > Labels: fetch > Fix For: 1.7 > > Attachments: NUTCH-1303.patch > > > as described in https://issues.apache.org/jira/browse/NUTCH-769, it is a good > solution to skip queues with high exception value, but it is not easy to set > value of fetcher.max.exceptions.per.queue when size of queues are different. > i suggest that define a ratio instead of value, so if the ratio of exceptions > per requests exceeds, then queue cleared. > also, it is not sufficient to keep fetcher from high exceptions, value of > fetcher.throughput.threshold.pages ensures that a valueable throughput of > fetch can gained against slow hosts, but it clean all queues not slow queue. > i suggest for this one that this factor like fetcher.max.exceptions.per.queue > enforce to each queue not all of them. -- This message is automatically generated by JIRA.
