> I started a DN on a machine that was completely out of space on one of its drives. I
saw the following:
> 2012-02-02 09:56:50,499 FATAL org.apache.hadoop.hdfs.server.datanode.DataNode: Initialization
failed for block pool Block pool BP-448349972-172.29.5.192-1323816762969 (storage id DS-507718931-172.29.5.194-11072-12978
> 42002148) service to styx01.sf.cloudera.com/172.29.5.192:8021
> java.io.IOException: Mkdirs failed to create /data/1/scratch/todd/styx-datadir/current/BP-448349972-172.29.5.192-1323816762969/tmp
>         at org.apache.hadoop.hdfs.server.datanode.FSDataset$BlockPoolSlice.<init>(FSDataset.java:335)
> but the DN continued to run, spewing NPEs when it tried to do block reports, etc. This
was on the HDFS-1623 branch but may affect trunk as well.
