------------------------------------------------------------
Key: HADOOP-1999
URL: https://issues.apache.org/jira/browse/HADOOP-1999
Project: Hadoop
Issue Type: Bug
Components: dfs
Affects Versions: 0.15.0
Environment: Sep 14 nightly build
Reporter: Christian Kunz
I restarted namenode with -upgrade option, started a few scripts running hadoop
command line utility to upload a few files into dfs, and ran at some time
hadoop dfsadmin -finalizeUpgrade.
At this time all the dfs clients I started before got stuck during block
transmission.
