Description

(Note: Some of the message are similar to HDFS-4201)

Just after i created a new HDFS cluster, and this time using Cloudera nightly RPM hadoop-hdfs-datanode-2.0.0+898-1.cdh4.2.0.p0.939.el6.x86_64, HDFS datanodes were unable to initialize or store anything. It stays alive, but keeps logging exceptions every few seconds.

It was "Initialization failed for block pool Block pool (...)" "org.apache.hadoop.util.DiskChecker$DiskErrorException: Invalid volume failure config value: 1" and then repeatedly "Exception in BPOfferService for Block pool (...)"

My config was :

<property>
<name>dfs.datanode.data.dir</name>
<value>file:///opt/hadoop/dn1/data</value>
</property>

After a bit of tweaking, it worked once i added a second EBS volume to the node. Yet it does not explain the initial error. A bug ?

<property>
<name>dfs.datanode.data.dir</name>
<value>file:///opt/hadoop/dn1/data,file:///opt/hadoop/dn2/data</value>
</property>

Original exceptions:
