>             Project: Hadoop HBase
>          Issue Type: Improvement
>            Reporter: Jean-Daniel Cryans
>             Fix For: 0.21.0
>
>
> In 0.19 I introduced a bandaid to limit the damage done to losing the RS holding META or ROOT by drastically lowering the memstore size. Example: 
> {code}
>   public static final HTableDescriptor ROOT_TABLEDESC = new HTableDescriptor(
>       HConstants.ROOT_TABLE_NAME,
>       new HColumnDescriptor[] { new HColumnDescriptor(HConstants.CATALOG_FAMILY,
>           10,  // Ten is arbitrary number.  Keep versions to help debuggging.
>           Compression.Algorithm.NONE.getName(), false, true, 8 * 1024,
>           HConstants.FOREVER, false) });
> {code}
> We can remove it from 0.21 since we force sync everything catalog.
