Todd Lipcon commented on HDFS-3391:
-----------------------------------
I was able to reproduce this by reapplying HDFS-3157 and adding the following
in DataNode.java:
{code}
---
a/hadoop-hdfs-project/hadoop-hdfs/src/main/java/org/apache/hadoop/hdfs/server/datanode/DataNode.java
+++
b/hadoop-hdfs-project/hadoop-hdfs/src/main/java/org/apache/hadoop/hdfs/server/datanode/DataNode.java
@@ -1983,6 +1983,13 @@ public class DataNode extends Configured
datanodes[i] = r.id;
storages[i] = r.storageID;
}
+ if (newBlock.getGenerationStamp() == 1005) {
+ try {
+ Thread.sleep(1500);
+ } catch (InterruptedException ie) {
+ Thread.currentThread().interrupt();
+ }
+ }
nn.commitBlockSynchronization(block,
newBlock.getGenerationStamp(), newBlock.getNumBytes(), true, false,
datanodes, storages);
{code}
I have to think through whether this is a bug which we've had for a while which
is uncovered by HDFS-3157, or if HDFS-3157 itself was incorrect.
