Hi,
I have a Hadoop instance (single node) installed on RHES5 running OK. The version of Hadoop is hdfs -version java version "1.7.0_25" Java(TM) SE Runtime Environment (build 1.7.0_25-b15) Java HotSpot(TM) 64-Bit Server VM (build 23.25-b01, mixed mode) I would like to add another file to namenode in hdfs-site.xml. That is effectively building resiliency and multi-plexing it. The new file will be on Solid State Disk. I tried adding it to hdfs-site.xml file by having <property> <name>dfs.namenode.name.dir</name> <value>file:/work/hadoop/hadoop_store/hdfs/namenode</value> </property> And changing it to <property> <name>dfs.namenode.name.dir</name> <value>file:/work/hadoop/hadoop_store/hdfs/namenode</value> <value>file:/ssddata6/hadoop/hadoop_store/hdfs/namenode</value> </property> But it does not work! Any ideas if one can add the secondary namenode file without losing data etc?
