Subject need some help about usage of hadoop
Date Wed, 19 Mar 2014 07:28:20 GMT
Recently, I always encounter a problem as following:

java.io.IOException: Bad connect ack with firstBadLink as
        at org.apache.hadoop.hdfs.DFSClient$DFSOutputStream.createBlockOutputStream(DFSClient.java:3139)
        at org.apache.hadoop.hdfs.DFSClient$DFSOutputStream.nextBlockOutputStream(DFSClient.java:3055)
        at org.apache.hadoop.hdfs.DFSClient$DFSOutputStream.access$1900(DFSClient.java:2305)
        at org.apache.hadoop.hdfs.DFSClient$DFSOutputStream$DataStreamer.run(DFSClient.java:2500)

and who can help me to address it?

and sometimes I got some error as following:

org.apache.hadoop.hdfs.DFSClient - Abandoning block blk_-2417465424319358936_104560494 

Overall, I doubt that it work not well because the pressure of the node or the network problem.

So, If you encounter them and solved them , please give me some help, Thank you so much.

Best Regards
