# The hbase command script. Based on the hadoop command script putting
# in hbase classes, libs and configurations ahead of hadoop's.
#
# TODO: Narrow the amount of duplicated code.
#
# Environment Variables:
#
# JAVA_HOME The java implementation to use. Overrides JAVA_HOME.
#
# HBASE_CLASSPATH Extra Java CLASSPATH entries.
#
# HBASE_CLASSPATH_PREFIX Extra Java CLASSPATH entries that should be
# prefixed to the system classpath.
#
# HBASE_HEAPSIZE The maximum amount of heap to use.
# Default is unset and uses the JVMs default setting
# (usually 1/4th of the available memory).
#
# HBASE_LIBRARY_PATH HBase additions to JAVA_LIBRARY_PATH for adding
# native libraries.
#
# HBASE_OPTS Extra Java runtime options.
#
# HBASE_CONF_DIR Alternate conf dir. Default is ${HBASE_HOME}/conf.
#
# HBASE_ROOT_LOGGER The root appender. Default is INFO,console
#
# JRUBY_HOME JRuby path: $JRUBY_HOME/lib/jruby.jar should exist.
# Defaults to the jar packaged with HBase.
#
# JRUBY_OPTS Extra options (eg '--1.9') passed to the hbase shell.
# Empty by default.
#
# HBASE_SHELL_OPTS Extra options passed to the hbase shell.
# Empty by default.
