ParseData's contentMeta accumulates unnecessary values during parse
-------------------------------------------------------------------
Key: NUTCH-535
URL: https://issues.apache.org/jira/browse/NUTCH-535
Project: Nutch
Issue Type: Bug
Affects Versions: 1.0.0
Reporter: Doğacan Güney
Assignee: Doğacan Güney
Fix For: 1.0.0
After NUTCH-506, if you run parse on a segment, parseData's contentMeta
accumulates metadata of every content parsed so far. This is because NUTCH-506
changed constructor to create a new metadata (before NUTCH-506, a new metadata
was created for every call to readFields). It seems hadoop somehow caches
Content instance so each new call to Content.readFields during ParseSegment
increases size of metadata. Because of this, one can end up with *huge*
parse_data directory (something like 10 times larger than content directory)
