Travis Thompson created HADOOP-10329:
----------------------------------------
Summary: Fully qualified URIs are inconsistant and sometimes break
in hadoop conf files
Key: HADOOP-10329
URL: https://issues.apache.org/jira/browse/HADOOP-10329
Project: Hadoop Common
Issue Type: Bug
Components: conf
Affects Versions: 2.2.0
Reporter: Travis Thompson
When specifying paths in the *-site.xml files, some are required to be fully
qualified, while others (specifically hadoop.tmp.dir) break when a fully
qualified uri is used.
Example:
If I set hadoop.tmp.dir in core-site to file:///something it'll create a file:
directory in my $PWD.
{noformat}
<property>
<name>hadoop.tmp.dir</name>
<value>file:///grid/a/tmp/hadoop-${user.name}</value>
</property>
{noformat}
{noformat}
[tthompso@test ~]$ tree file\:/
file:/
└── grid
└── a
└── tmp
└── hadoop-tthompso
{noformat}
Other places, like the datanode, or the nodemanager, will complain if I don't
use fully qualified uris
{noformat}
<property>
<name>dfs.datanode.data.dir</name>
<value>/grid/a/dfs-data/bs</value>
</property>
{noformat}
{noformat}
WARN org.apache.hadoop.hdfs.server.common.Util: Path /grid/a/dfs-data/bs should
be specified as a URI in configuration files. Please update hdfs configuration.
