we want deploy one more data-center for data safe.
As we rebuild one node's data from the old DC, after some hours rebuild failure
due to network fault.
I can restart rebuild surely,but I'm afraid restart rebuild,
is it rebuild all rang of tokens which belong to the node or just rebuild the
rest rang of tokens from last rebuild.(since last rebuild we get some data).
As I view the source, I see this code.
class RangeStreamer method getRangeFetchMap
private static Multimap<InetAddress, Range<Token>>
getRangeFetchMap(Multimap<Range<Token>, InetAddress> rangesWithSources,
Collection<ISourceFilter> sourceFilters, String keyspace)
{
Multimap<InetAddress, Range<Token>> rangeFetchMapMap =
HashMultimap.create();
for (Range<Token> range : rangesWithSources.keySet())
{
boolean foundSource = false;
outer:
for (InetAddress address : rangesWithSources.get(range))
{
if (address.equals(FBUtilities.getBroadcastAddress()))
{
// If localhost is a source, we have found one, but we
don't add it to the map to avoid streaming locally
foundSource = true;
continue;
}
for (ISourceFilter filter : sourceFilters)
{
if (!filter.shouldInclude(address))
continue outer;
}
rangeFetchMapMap.put(address, range);
foundSource = true;
break; // ensure we only stream from one other node for each
range
}
if (!foundSource)
throw new IllegalStateException("unable to find sufficient
sources for streaming range " + range + " in keyspace " + keyspace);
}
return rangeFetchMapMap;
}
The bold，when found the address is localhost, It continue to find others and
then put into the rangeFetchMapMap。
I think the continue key word should be break, if it just want rebuild the data
it doesn't have. Is it right?
Best regards!
