Failure to replicate dfs block kills client
-------------------------------------------
Key: HADOOP-128
URL: http://issues.apache.org/jira/browse/HADOOP-128
Project: Hadoop
Type: Bug
Components: dfs
Versions: 0.1.1
Environment: ~200 node linux cluster (kernel 2.6, redhat, 2 hyper threaded
cpus)
Reporter: Owen O'Malley
Assigned to: Owen O'Malley
When the datanode gets an exception, which is logged as:
060407 155835 13 DataXCeiver
java.io.EOFException
at java.io.DataInputStream.readFully(DataInputStream.java:178)
at java.io.DataInputStream.readLong(DataInputStream.java:380)
at org.apache.hadoop.dfs.DataNode$DataXceiver.run(DataNode.java:462)
at java.lang.Thread.run(Thread.java:595)
It closes the user's connection to the data node, which causes the client to
get an IOException from:
at java.io.DataInputStream.readFully(DataInputStream.java:178)
at java.io.DataInputStream.readLong(DataInputStream.java:380)
at
org.apache.hadoop.dfs.DFSClient$DFSOutputStream.internalClose(DFSClient.java:883)
