Subject Start standby namenode using bootstrapStandby hangs
Date Wed, 10 Sep 2014 09:02:18 GMT
Hi Experts,

My hadoop cluster is enabled HA with QJM and I failed to upgrade it from
version 2.2.0 to 2.4.1. Why? Is this a existing issue?

My steps:
1. Stop hadoop cluster
2. On each node, upgrade hadoop binary with the newer version
3. On each JournalNode:
sbin/hadoop-daemon.sh start journalnode
4. On each DataNode:
sbin/hadoop-daemon.sh start datanode
5. On previous active NameNode:
sbin/hadoop-daemon.sh start namenode -upgrade
6. On previous standby NameNode:
sbin/hadoop-daemon.sh start namenode -bootstrapStandby

Encountered Issue:
Failed to start NameNode service normally with a warning info as below:
2014-09-10 15:57:41,730 WARN org.apache.hadoop.hdfs.server.common.Util:
Path /hadoop/hdfs/name should be specified as a URI in configuration files.
Please update hdfs configuration.
After throwing out above warning info, the execution of command hangs there
and did not throw any other warning/error messages any more.
