Class org.apache.hadoop.hbase.client.HTableInterface

Examples of org.apache.hadoop.hbase.client.HTableInterface.batch()

org.apache.hadoop.hbase.client.HTableInterface.batch()
Method that does a batch call on Deletes, Gets, Puts, Increments, Appends and RowMutations. The ordering of execution of the actions is not defined. Meaning if you do a Put and a Get in the same {@link #batch} call, you will not necessarily beguaranteed that the Get returns what the Put had put. @param actions list of Get, Put, Delete, Increment, Append, RowMutations objects @param results Empty Object[], same size as actions. Provides access to partialresults, in case an exception is thrown. A null in the result array means that the call for that action failed, even after retries @throws IOException @since 0.90.0
