DN continues to start up, even if block pool fails to initialize
----------------------------------------------------------------
Key: HDFS-2882
URL: https://issues.apache.org/jira/browse/HDFS-2882
Project: Hadoop HDFS
Issue Type: Bug
Components: data-node
Affects Versions: 0.24.0
Reporter: Todd Lipcon
Assignee: Todd Lipcon
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.
