[jira] Created: (HADOOP-3432) NetUtils.createSocketAddr NPEs if
dfs.datanode.ipc.address is not set for a data node
NetUtils.createSocketAddr NPEs if dfs.datanode.ipc.address is not set for a data node
-------------------------------------------------------------------------------------
Key: HADOOP-3432
URL: https://issues.apache.org/jira/browse/HADOOP-3432
Project: Hadoop Core
Issue Type: Bug
Components: dfs
Affects Versions: 0.18.0
Reporter: Steve Loughran
Priority: Minor
DataNode.startDatanode assumes that a configuration always returns a non-null dfs.datanode.ipc.address value, as the result is passed straight down to NetUtils.createSocketAddr
InetSocketAddress ipcAddr = NetUtils.createSocketAddr(
conf.get("dfs.datanode.ipc.address"));
which triggers an NPE
Caused by: java.lang.NullPointerException
at org.apache.hadoop.net.NetUtils.createSocketAddr(NetUtils.java:130)
