-------------------------------------
Summary: Synchronize invalidateBlocks in DatanodeDescriptor
Key: HDFS-14798
URL: https://issues.apache.org/jira/browse/HDFS-14798
Project: Hadoop HDFS
Issue Type: Bug
Components: namenode
Affects Versions: 3.2.0
Reporter: David Mollitor
{code:java|title=DatanodeDescriptor.java}
public void resetBlocks() {
...
this.invalidateBlocks.clear();
...
}
public void clearBlockQueues() {
synchronized (invalidateBlocks) {
this.invalidateBlocks.clear();
}
...
}
{code}
It may not be strictly necessary, but why risk it? The invalidateBlocks should
be protected in {{resetBlocks()}} just like it is in {{clearBlockQueues()}}/
