Description
HBase seems to fail to add HADOOP_CONF_DIR to its classpath and thus can't access Hadoop configuration files (such as core-site.xml, etc.). This can manifest itself in various ways including HBase failing to authenticate against a secure Hadoop cluster.
Workaround: add the following to /etc/hbase/conf/hbase-env.sh
export HBASE_CLASSPATH=/etc/hadoop/conf
