------------------------------------
Summary: Log better message when Hadoop configuration files are
not found
Key: ACCUMULO-1973
URL: https://issues.apache.org/jira/browse/ACCUMULO-1973
Project: Accumulo
Issue Type: Improvement
Affects Versions: 1.5.0
Reporter: Josh Elser
Fix For: 1.4.5, 1.5.1, 1.6.0
I keep running into this -- with the introduction of Hadoop-2 into the
configuration, if you don't properly set HADOOP_CONF_DIR, you'll get the
"default" instance.dfs.uri (I believe) which will (almost) always not work out
for you.
You get a strange stack trace around ChecksumFileSystem or FilterFileSystem,
but the underlying problem is that your configuration is likely pointing at the
wrong configuration directory for Hadoop ($HADOOP_PREFIX/conf instead of
$HADOOP_PREFIX/etc/hadoop, or vice versa).
We should be able to do something that makes this more intuitive to new-comers
with printing error messages.
