[jira] Created: (HADOOP-5594) NameNode entered into an infinite
loop of logging
NameNode entered into an infinite loop of logging
-------------------------------------------------
Key: HADOOP-5594
URL: https://issues.apache.org/jira/browse/HADOOP-5594
Project: Hadoop Core
Issue Type: Bug
Components: dfs
Affects Versions: 0.19.0
Reporter: Runping Qi
We have a cluster running Hadoop 0.19.0.
For some reason, the name node entered into an infinite loop of spitting the following message once every second:
2009-03-30 00:00:02,658 INFO org.apache.hadoop.hdfs.server.namenode.FSNamesystem: commitBlockSynchronization(lastblock=blk_2800657178116909860_14611, newgenerationstamp=0, newlength=0, newtargets=[])

[jira] Commented: (HADOOP-5594) NameNode entered into an infinite
loop of logging
Posted by "Hairong Kuang (JIRA)" <ji...@apache.org>.

Hairong Kuang commented on HADOOP-5594:
---------------------------------------
This infinite retry loop might be cased by the same problem reported in HADOOP-5311. The infinite retry got fixed in HADOOP-3998. Runping, could you please check the dfs client log to provide us more information?
