Class TransactionAwareHTable

java.lang.Object
  co.cask.tephra.hbase96.TransactionAwareHTable

All Implemented Interfaces:

TransactionAware, Closeable, org.apache.hadoop.hbase.client.HTableInterface

public class TransactionAwareHTable
extends Object
implements org.apache.hadoop.hbase.client.HTableInterface, TransactionAware

A Transaction Aware HTable implementation for HBase 0.96. Operations are committed as usual, but upon a failed or aborted transaction, they are rolled back to the state before the transaction was started.

Constructor Summary

TransactionAwareHTable(org.apache.hadoop.hbase.client.HTable hTable)
Create a transactional aware instance of the passed HTable

TransactionAwareHTable(org.apache.hadoop.hbase.client.HTable hTable, boolean allowNonTransactional)
Create a transactional aware instance of the passed HTable, with the option of allowing non-transactional operations.
