> In the inaccurately-named IndexWriter.writeAndKillYourselfOnFailure, there's
> the following code:
> {code:java}
> public void writeAndKillYourselfOnFailure(Collection<Pair<Mutation, byte[]>>
> indexUpdates, boolean allowLocalUpdates, int clientVersion) throws
> IOException {
> // convert the strings to htableinterfaces to which we can talk and group by
> TABLE Multimap<HTableInterfaceReference, Mutation> toWrite =
> resolveTableReferences(indexUpdates);
> writeAndKillYourselfOnFailure(toWrite, allowLocalUpdates, clientVersion);
> writeAndHandleFailure(toWrite, allowLocalUpdates, clientVersion);
> }
> {code}
> writeAndKillYourselfOnFailure and writeAndHandleFailure seem to be identical,
> which means that calling them both will result in the same index Cells being
> written twice. This shouldn't affect correctness, but it will affect
> performance and (temporarily, until compaction) storage
