Description

hbase.offheapcache.percentage is unused now.

<property>
    <name>hbase.offheapcache.percentage</name>
    <value>0</value>
    <description>The percentage of the off heap space (-XX:MaxDirectMemorySize) to be
     allocated towards the experimental off heap "SlabCache" (This is different to
     the BucketCache -- see the package javadoc for org.apache.hadoop.hbase.io.hfile
     for more on your options). If you desire the cache to be disabled, simply set this
      value to 0.</description>
