Jonathan Ellis commented on CASSANDRA-362:
------------------------------------------
01 and 02 are renaming and cleanup.
03 has fixes for 4 separate bugs that colluded to break this. :)
+ tableKeysCachedFractions_.put("system", 0.01);
this is required to flush now, so we need to generate it for the system table
(keyspace).
- /* TODO: Remove this to not process Hints */
for some reason FB decided not to replay writes to the system tables. the
comment indicates that this was an optimization for hinted handoff, but if
there isn't much hinted handoff data, then replaying isn't a Big Deal, and if
there _is_ a lot then you probably don't want to throw it away.
this was biting us here since we moved the token/generation info into the
system table instead of a special-cased file.
+ QueryFilter filter = new IdentityQueryFilter(LOCATION_KEY, new
QueryPath(LOCATION_CF));
the old query only fetched generation. this is the easiest way to fetch the
whole CF.
+ return ColumnFamily.create(getTableName(), getColumnFamilyName());
old code was broken (passing null in several places). not sure why; didn't
investigate too closely since the new code is the more straightforward solution
anyway.

> If you set InititalToken to "" and restart cassandra it should generate a
> initialtoken and store it in the SystemTable so that next time it is not

> generated every time.
