> Remove META and ROOT memcache size bandaid
> -------------------------------------------
>
> Key: HBASE-1945
> URL: https://issues.apache.org/jira/browse/HBASE-1945
> 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.
