Subject Re: how to define a column family as a "essential column family"
Date Thu, 06 Jun 2013 02:06:47 GMT
Take a look at release notes for HBASE-5416.
Below is from SingleColumnValueFilter:

  public boolean isFamilyEssential(byte[] name) {

    return !this.filterIfMissing || Bytes.equals(name, this.columnFamily);

  }
Also refer to TestJoinedScanners

Cheers
