org.apache.hadoop.hbase.client.HTable.checkAndDelete()
{@inheritDoc}
org.apache.hadoop.hbase.client.HTableInterface.checkAndDelete()
Atomically checks if a row/family/qualifier value matches the expected value. If it does, it adds the delete. If the passed value is null, the check is for the lack of column (ie: non-existance) @param row to check @param family column family to check @param qualifier column qualifier to check @param value the expected value @param delete data to delete if check succeeds @throws IOException e @return true if the new delete was executed, false otherwise
