Fengdong Yu updated HDFS-5553:
------------------------------
Description:
As HDFS-5550 depicted, journal nodes doesn't upgrade, so I change the VERSION
manually according to NN's VERSION.
then , I do upgrade and get this exception.
my steps as following:
It's a fresh cluster with hadoop-2.0.1 before upgrading.
0) install hadoop-2.2.0 hadoop package on all nodes.
1) stop-dfs.sh on active NN
2) disable HA in the core-site.xml and hdfs-site.xml on active NN and SNN
3) start-dfs.sh -upgrade -clusterId test-cluster on active NN(only one NN now.)
4) stop-dfs.sh after active NN started successfully.
5) enable HA in the core-site.xml and hdfs-site.xml on active NN and SNN
6) change all journal nodes' VERSION manually according to NN's VERSION
7) rm -f 'dfs.journalnode.edits.dir'/test-cluster/current/* (just keep VERSION
here)
8) delete all data under 'dfs.namenode.name.dir' on SNN
9) scp -r 'dfs.namenode.name.dir' to SNN on active NN
10) start-dfs.sh
