[jira] Created: (HADOOP-258) Cannot obtain block errors
Cannot obtain block errors
--------------------------
Key: HADOOP-258
URL: http://issues.apache.org/jira/browse/HADOOP-258
Project: Hadoop
Type: Bug
Components: dfs
Versions: 0.3
Reporter: Owen O'Malley
Assigned to: Sameer Paranjpye
I've been seeing a lot of errors from dfs for the last couple days. The exception that I see is:
java.io.IOException: Could not obtain block: blk_2867431916903738534 file=/user/oom/big-rand/part000271 offset=0 at org.apache.hadoop.dfs.DFSClient$DFSInputStream.blockSeekTo(DFSClient.java:532) at org.apache.hadoop.dfs.DFSClient$DFSInputStream.read(DFSClient.java:641) at org.apache.hadoop.fs.FSDataInputStream$Checker.read(FSDataInputStream.java:83) at org.apache.hadoop.fs.FSDataInputStream$PositionCache.read(FSDataInputStream.java:158) at java.io.BufferedInputStream.fill(BufferedInputStream.java:218) at java.io.BufferedInputStream.read1(BufferedInputStream.java:256) at java.io.BufferedInputStream.read(BufferedInputStream.java:313) at java.io.DataInputStream.readFully(DataInputStream.java:176) at java.io.DataInputStream.readFully(DataInputStream.java:152) at org.apache.hadoop.io.SequenceFile$Reader.init(SequenceFile.java:264) at org.apache.hadoop.io.SequenceFile$Reader.(SequenceFile.java:248) at org.apache.hadoop.io.SequenceFile$Reader.(SequenceFile.java:238) at org.apache.hadoop.mapred.SequenceFileRecordReader.(SequenceFileRecordReader.java:36) at org.apache.hadoop.mapred.SequenceFileInputFormat.getRecordReader(SequenceFileInputFormat.java:53) at org.apache.hadoop.mapred.MapTask.run(MapTask.java:105) at org.apache.hadoop.mapred.TaskTracker$Child.main(TaskTracker.java:866)
I haven't had my fingers in that code recently, does it ring any bells for anyone?

[jira] Commented: (HADOOP-258) Cannot obtain block errors

Chris Schneider commented on HADOOP-258:
----------------------------------------
Just FYI, I recently integrated hadoop 0.5 into my copy of the source, rebuit and installed. I ran into similar "Could not obtain block" errors until I realized that I hadn't deployed the (new in hadoop 0.5) .../webapps/datanode/ servlet on my cluster.
