[jira] [Created] (CASSANDRA-3305) LeveledCompactionStrategy fails
to remove compacted files on Windows
LeveledCompactionStrategy fails to remove compacted files on Windows
--------------------------------------------------------------------
Key: CASSANDRA-3305
URL: https://issues.apache.org/jira/browse/CASSANDRA-3305
Project: Cassandra
Issue Type: Bug
Components: Core
Affects Versions: 1.0.0
Reporter: Radim Kolar
very common message on windows server:
ERROR [NonPeriodicTasks:1] 2011-10-04 15:47:40,508 SSTableDeletingTask.java (lin
e 76) Unable to delete \var\lib\cassandra\data\test\sipdb-h-302-Data.db (it will
be removed on server restart; we'll also retry after GC)
As far i can see they are not removed even 1 hour later, successfully wasting disk space. If i force GC via jconsole, they are deleted. Old compaction strategy does not have this problem.

[jira] [Commented] (CASSANDRA-3305) LeveledCompactionStrategy fails

Jonathan Ellis commented on CASSANDRA-3305:
-------------------------------------------
I haven't been able to reproduce this.
I inserted 11M rows on Windows 7 (built from current trunk), resulting in 1205 compactions. (Added stress.bat to make this easier in r1179415.) I didn't see any instances of this error, nor do I see anything along the lines of CASSANDRA-3318 that would apply to leveled compaction but not size-tiered.

----------------------------------------
i can reproduce it easily with rc2. Maybe its timing dependent and it will not show on faster computers? i have old Pentium D, 100% CPU used during stress testing.
