Hbase should use a HADOOP_HOME environment variable if available.
-----------------------------------------------------------------
Key: HBASE-3465
URL: https://issues.apache.org/jira/browse/HBASE-3465
Project: HBase
Issue Type: Bug
Affects Versions: 0.90.0
Reporter: Ted Dunning
Fix For: 0.90.1, 0.92.0
I have been burned a few times lately while developing code by having the make
sure that the hadoop jar in hbase/lib is exactly correct. In my own
deployment, there are actually 3 jars and a native library to keep in sync that
hbase shouldn't have to know about explicitly. A similar problem arises when
using stock hbase with CDH3 because of the security patches changing the wire
protocol.
All of these problems could be avoided by not assuming that the hadoop library
is in the local directory. Moreover, I think it might be possible to assemble
the distribution such that the compile time hadoop dependency is in a cognate
directory to lib and is referenced using a default value for HADOOP_HOME.
Does anybody have any violent antipathies to such a change?
