[jira] Created: (CASSANDRA-902) Bootstrapping might skip needed
ranges.
Bootstrapping might skip needed ranges.
---------------------------------------
Key: CASSANDRA-902
URL: https://issues.apache.org/jira/browse/CASSANDRA-902
Project: Cassandra
Issue Type: Bug
Affects Versions: 0.6
Reporter: Gary Dusbabek
Assignee: Gary Dusbabek
Fix For: 0.6
Bootstrapper.getRangeWithSources should return a multimap with as many keys as myRangeAddresses. But with the way the two loops are structured, they are not guaranteed to ever examine all of myRanges. To see why, consider a scenario where the inner-loop breaks on the first element in myRanges. myRangeAddresses will only ever have one key in it.
Solution is to swap the order of the loops.

Gary Dusbabek updated CASSANDRA-902:
------------------------------------
Attachment: bootstrap-range-addr-calculation.txt
patched against trunk. The same code exists in 5, so is likely a problem there too.
