Hi:Jonathan
I have found out what's going wrong.
I change the configuration
1440

there are a few hint records writen to many commitlog segment.

Hi:all
In my little cluter ,after i insert many many records into cassandra, there
are hundreds of commit log files in commitlog log directory.
is it normal ?
I read the source code of commitlog , there shouldn't be so many commitlog
log files .
any clue will be appreciate.

lerate the GC
process.
try
{
r.cleanup();
r.clear();
}
catch (IOException e)
{
logger.error("Error deleting " + r.path, e);
}
