Subject [jira] [Commented] (HBASE-9097) Set HBASE_CLASSPATH before rest of the classpath
Date Fri, 11 Oct 2013 04:02:49 GMT

    [ https://issues.apache.org/jira/browse/HBASE-9097?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13792316#comment-13792316
] 

Lars Hofhansl commented on HBASE-9097:
--------------------------------------

I see. Do the YCSB parts compiled against HBase 0.90.5 run fine against an actual 0.94 or
0.96 HBase?
It seems in one case we are expected wire compatibility and in the other we are expecting
binary compatibility.

> 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.
