One thing that is different for Kafka, is that all heap-related arguments will be passed in via the env variable `HBASE_HEAPSIZE`, all the other ones via `HBASE_OPTS`, `HBASE_MASTER_OPTS`, `HBASE_REGIONSERVER_OPTS` and `HBASE_REST_OPTS`.
The `HBASE_HEAPSIZE` variable is documented as follows in the https://cwiki.apache.org/confluence/display/HADOOP2/Hbase+FAQ+Operations[HBase FAQs]:

> Set the HBASE_HEAPSIZE environment variable in ${HBASE_HOME}/conf/hbase-env.sh if your install needs to run with a larger heap.
> HBASE_HEAPSIZE is like HADOOP_HEAPSIZE in that its value is the desired heap size in MB.

> `HBASE_HEAPSIZE` is like `HADOOP_HEAPSIZE` in that its value is the desired heap size in MB.
> The surrounding '-Xmx' and 'm' needed to make up the maximum heap size java option are added by the hbase start script

Looking at `bin/hbase`, you can actually add the `m` suffix to make the unit more clear, the script will detect this https://github.com/apache/hbase/blob/777010361abb203b8b17673d84acf4f7f1d0283a/bin/hbase#L165[here] and work correctly.
