--------------------------------------
Summary: Zookeeper auto purge process does not purge files
Key: ZOOKEEPER-2844
URL: https://issues.apache.org/jira/browse/ZOOKEEPER-2844
Project: ZooKeeper
Issue Type: Bug
Affects Versions: 3.4.6
Environment: Windows Server 2008 R2
Reporter: Avi Steiner
I'm using Zookeeper 3.4.6
The ZK log data folder keeps growing with transaction logs files (log.*).
I set the following in zoo.cfg:
autopurge.purgeInterval=1
autopurge.snapRetainCount=3
dataDir=..\\data
Per ZK log, it reads those parameters:
2017-07-13 10:36:21,266 [myid:] - INFO [main:DatadirCleanupManager@78] -
autopurge.snapRetainCount set to 3
2017-07-13 10:36:21,266 [myid:] - INFO [main:DatadirCleanupManager@79] -
autopurge.purgeInterval set to 1
It also says that cleanup process is running:
2017-07-13 10:36:21,266 [myid:] - INFO
[PurgeTask:DatadirCleanupManager$PurgeTask@138] - Purge task started.
2017-07-13 10:36:21,297 [myid:] - INFO
[PurgeTask:DatadirCleanupManager$PurgeTask@144] - Purge task completed.
But actually nothing is deleted.
Every service restart, a new file is created.
The only parameter I managed to change is preAllocSize, which means the minimum
size per file. The default is 64MB. I changed it to 10KB only for testing, and
I swa the effect as expected: new files were created with 10KB.
I also tried to create a batch file that will run the following:
java -cp
zookeeper-3.4.6.jar;lib/slf4j-api-1.6.1.jar;lib/slf4j-log4j12-1.6.1.jar;lib/log4j-1.2.16.jar;conf
org.apache.zookeeper.server.PurgeTxnLog .\data -n 3
But it still doesn't do the job.
Please advise.
