@@ -76,6 +76,7 @@ Following options can be configurable using `-p`.
* `principal`: If testing need to be done against a secure HBase cluster using Kerberos Keytab,
this property can be used to pass the principal in the keytab file.
* `keytab`: The Kerberos keytab file name and location can be passed through this property.
-* `writebuffersize`: The maximum amount, in bytes, of data to buffer on the client side before a flush is forced. The default is 12MB.
+* `clientbuffering`: Whether or not to use client side buffering and batching of write operations. This can significantly improve performance and defaults to true.
+* `writebuffersize`: The maximum amount, in bytes, of data to buffer on the client side before a flush is forced. The default is 12MB. Only used when `clientbuffering` is true.
Additional HBase settings should be provided in the `hbase-site.xml` file located in your `/HBASE-HOME-DIR/conf` directory. Typically this will be `/etc/hbase/conf`.
