I have managed to get my server backup and running after struggling for 2
weeks, however only 3 of the 6 nodes are up, the ones not working give the
following error in the tasktracker log of one of the failed data nodes.
2014-01-16 13:44:12,999 ERROR org.apache.hadoop.mapred.TaskTracker: Caught
exception: java.net.ConnectException: Call From
Node06.xxx.xx.xx/xx.xxx.xxx.xxx to Node02.xxx.xx.xx:8021 failed on
connection exception: java.net.ConnectException: Connection refused; For
more details see: http://wiki.apache.org/hadoop/ConnectionRefused
Caused by: java.net.ConnectException: *Connection refused.*
I have looked in the Jobtracker logs but nothing is mentioned regarding
Node02 is listening on port 8021, as it has successfully connected to 3 of
the Nodes(02,04,05) and is listening still.
Not sure why this is happening.
