ConcurrentModificationException in invalidateCorruptReplicas()
--------------------------------------------------------------
Key: HDFS-606
URL: https://issues.apache.org/jira/browse/HDFS-606
Project: Hadoop HDFS
Issue Type: Bug
Components: name-node
Affects Versions: 0.21.0
Reporter: Konstantin Shvachko
Assignee: Konstantin Shvachko
Fix For: 0.21.0
{{BlockManager.invalidateCorruptReplicas()}} iterates over DatanodeDescriptor-s
while removing corrupt replicas from the descriptors. This causes
{{ConcurrentModificationException}} if there is more than one replicas of the
block. I ran into this exception debugging different scenarios in append, but
it should be fixed in the trunk too.
