Subject [jira] [Created] (HBASE-9097) Set HBASE_CLASSPATH before rest of the classpath
Date Wed, 31 Jul 2013 01:41:49 GMT
Jesse Yates created HBASE-9097:
----------------------------------

             Summary: Set HBASE_CLASSPATH before rest of the classpath
                 Key: HBASE-9097
                 URL: https://issues.apache.org/jira/browse/HBASE-9097
             Project: HBase
          Issue Type: Bug
          Components: scripts
    Affects Versions: 0.98.0, 0.95.2, 0.94.11
            Reporter: Jesse Yates
            Assignee: Jesse Yates


We encountered this when one of the hadoop test jars (specifically hadoop-mapreduce-client-jobclient-2.0.0-cdh4.3.0-tests.jar,
but that's beside the point) had an hdfs-site.xml. This clobbered the hdfs-site.xml that we
included on the classpath via HBASE_CLASSPATH in hbase-env.sh, meaning the master didn't start
in HA NN mode, because the proxy-provider wasn't found in the hdfs-site.xml from the test
jar (even though it was in our config file) because that was the first resolution of that
file.

This should be a fairly simple fix in bin/hbase, but has some potentially wide-ranging effects
on existing installs that just 'happen' to work.

Generally, I'd expect things set on the HBASE_CLASSPATH to take precedence over anything else
when starting the hbase daemon.
