Hi All, I am new to Hadoop. I was able to 3 datanode running and working. I purposefully shutdown one datanode and execute "bin/hadoop fs -copyFromLocal ../hadoop.sh /user/coka/somedir/slave02-datanodeDown" to see what happen.
The execution fails with the exception below. Why it is so ? Thanks in advance. Cheers TS 12/01/05 15:41:40 INFO hdfs.DFSClient: Exception in createBlockOutputStream java.io.IOException: Bad connect ack with firstBadLink as 192.160.1.103:50010 12/01/05 15:41:40 INFO hdfs.DFSClient: Abandoning block blk_-4266327738363863152_1008 12/01/05 15:41:40 INFO hdfs.DFSClient: Waiting to find target node: 192.160.1.4:50010 12/01/05 15:41:49 INFO hdfs.DFSClient: Exception in createBlockOutputStream java.io.IOException: Bad connect ack with firstBadLink as 192.160.1.103:50010 12/01/05 15:41:49 INFO hdfs.DFSClient: Abandoning block blk_1476878908693006667_1008 12/01/05 15:42:13 INFO hdfs.DFSClient: Exception in createBlockOutputStream java.io.IOException: Bad connect ack with firstBadLink as 192.160.1.103:50010 12/01/05 15:42:13 INFO hdfs.DFSClient: Abandoning block blk_-7529382935054091141_1008 12/01/05 15:42:13 INFO hdfs.DFSClient: Waiting to find target node: 192.160.1.4:50010 12/01/05 15:42:22 INFO hdfs.DFSClient: Exception in createBlockOutputStream java.io.IOException: Bad connect ack with firstBadLink as 192.160.1.103:50010 12/01/05 15:42:22 INFO hdfs.DFSClient: Abandoning block blk_375095740848321980_1008 12/01/05 15:42:28 WARN hdfs.DFSClient: DataStreamer Exception: java.io.IOException: Unable to create new block. at org.apache.hadoop.hdfs.DFSClient$DFSOutputStream.nextBlockOutputStream(DFSClient.java:3002) at org.apache.hadoop.hdfs.DFSClient$DFSOutputStream.access$2000(DFSClient.java:2255) at org.apache.hadoop.hdfs.DFSClient$DFSOutputStream$DataStreamer.run(DFSClient.java:2446) 12/01/05 15:42:28 WARN hdfs.DFSClient: Error Recovery for block blk_375095740848321980_1008 bad datanode[1] nodes == null 12/01/05 15:42:28 WARN hdfs.DFSClient: Could not get block locations.
