@rem Set environment variables here.

@rem The java implementation to use.  Java 1.7+ required.
@rem set JAVA_HOME=c:\apps\java

@rem Extra Java CLASSPATH elements.  Optional.
@rem set HBASE_CLASSPATH=

@rem The maximum amount of heap to use. Default is left to JVM default.
@rem set HBASE_HEAPSIZE=1000

@rem Uncomment below if you intend to use off heap cache. For example, to allocate 8G of 
@rem offheap, set the value to "8G".
@rem set HBASE_OFFHEAPSIZE=1000

@rem For example, to allocate 8G of offheap, to 8G:
@rem etHBASE_OFFHEAPSIZE=8G

@rem Extra Java runtime options.
@rem Below are what we set by default.  May only work with SUN JVM.
@rem For more on why as well as other possible settings,
@rem see http://hbase.apache.org/book.html#performance
@rem JDK6 on Windows has a known bug for IPv6, use preferIPv4Stack unless JDK7.
@rem @rem See TestIPv6NIOServerSocketChannel.
set HBASE_OPTS="-XX:+UseConcMarkSweepGC" "-Djava.net.preferIPv4Stack=true"

@rem Configure PermSize. Only needed in JDK7. You can safely remove it for JDK8+
set HBASE_MASTER_OPTS=%HBASE_MASTER_OPTS% "-XX:PermSize=128m" "-XX:MaxPermSize=128m"
set HBASE_REGIONSERVER_OPTS=%HBASE_REGIONSERVER_OPTS% "-XX:PermSize=128m" "-XX:MaxPermSize=128m"

@rem Uncomment below to enable java garbage collection logging for the server-side processes
@rem this enables basic gc logging for the server processes to the .out file
@rem set SERVER_GC_OPTS="-verbose:gc" "-XX:+PrintGCDetails" "-XX:+PrintGCDateStamps" %HBASE_GC_OPTS%

@rem this enables gc logging using automatic GC log rolling. Only applies to jdk 1.6.0_34+ and 1.7.0_2+. Either use this set of options or the one above
@rem set SERVER_GC_OPTS="-verbose:gc" "-XX:+PrintGCDetails" "-XX:+PrintGCDateStamps" "-XX:+UseGCLogFileRotation" "-XX:NumberOfGCLogFiles=1" "-XX:GCLogFileSize=512M" %HBASE_GC_OPTS%

@rem Uncomment below to enable java garbage collection logging for the client processes in the .out file.
@rem set CLIENT_GC_OPTS="-verbose:gc" "-XX:+PrintGCDetails" "-XX:+PrintGCDateStamps" %HBASE_GC_OPTS%

@rem Uncomment below (along with above GC logging) to put GC information in its own logfile (will set HBASE_GC_OPTS)
@rem set HBASE_USE_GC_LOGFILE=true

@rem Uncomment and adjust to enable JMX exporting
@rem See jmxremote.password and jmxremote.access in $JRE_HOME/lib/management to configure remote password access.
@rem More details at: http://java.sun.com/javase/6/docs/technotes/guides/management/agent.html

@rem set HBASE_JMX_BASE="-Dcom.sun.management.jmxremote.ssl=false" "-Dcom.sun.management.jmxremote.authenticate=false"

@rem set HBASE_ZOOKEEPER_OPTS=%HBASE_JMX_BASE% -Dcom.sun.management.jmxremote.port=10104"

@rem File naming hosts on which HRegionServers will run.  $HBASE_HOME/conf/regionservers by default.
@rem set HBASE_REGIONSERVERS=%HBASE_HOME%\conf\regionservers

@rem Where log files are stored.  $HBASE_HOME/logs by default.
@rem set HBASE_LOG_DIR=%HBASE_HOME%\logs

@rem A string representing this instance of hbase. $USER by default.
@rem set HBASE_IDENT_STRING=%USERNAME%

@rem Seconds to sleep between slave commands.  Unset by default.  This
@rem can be useful in large clusters, where, e.g., slave rsyncs can
@rem otherwise arrive faster than the master can service them.
@rem set HBASE_SLAVE_SLEEP=0.1

@rem Tell HBase whether it should manage it's own instance of Zookeeper or not.
@rem set HBASE_MANAGES_ZK=true
