Shai Erera updated LUCENE-4975: ------------------------------- Attachment: LUCENE-4975.patch bq. maybe also call MDW.setRandomIOExceptionRateOnOpen Thanks Mike! I added that and a slew of problems surfaced, most of them in the test, but I improved the handlers' implementation to cleanup after themselves if e.g. a copy or sync to the handlerDir failed. While this wasn't a bug, it leaves the target index directory clean. There's one nocommit which bugs me though -- I had to add dir.setPreventDoubleWrite(false) because when the handler fails during copying of say _2.fdt to the index dir, the file is deleted from the indexDir, and the client re-attemts to upgrade. At this point, MDW complains that _2.fdt was already written to, even though I deleted it. Adding this setPrevent was the only way I could make MDW happy, but I don't like it since I do want to catch errors in the handler/client if they e.g. attempt to copy over an existing file. Maybe we can make MDW respond somehow to delete()? I know that has bad implications on its own, e.g. code which deletes and then accidentally recreates files with older names ... any ideas? > Add Replication module to Lucene > -------------------------------- > > Key: LUCENE-4975 > URL: https://issues.apache.org/jira/browse/LUCENE-4975 > Project: Lucene - Core > Issue Type: New Feature > Reporter: Shai Erera > Assignee: Shai Erera > Attachments: LUCENE-4975.patch, LUCENE-4975.patch, LUCENE-4975.patch, > LUCENE-4975.patch, LUCENE-4975.patch > > > I wrote a replication module which I think will be useful to Lucene users who > want to replicate their indexes for e.g high-availability, taking hot backups > etc. > I will upload a patch soon where I'll describe in general how it works. -- This message is automatically generated by JIRA.
