Subject [jira] Created: (HBASE-1945) Remove META and ROOT memcache size bandaid
Date Fri, 30 Oct 2009 04:20:59 GMT
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: 

  public static final HTableDescriptor ROOT_TABLEDESC = new HTableDescriptor(
      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) });

We can remove it from 0.21 since we force sync everything catalog.
