Examples of org.apache.hadoop.hbase.io.BatchUpdate.startUpdate()

org.apache.hadoop.hbase.io.BatchUpdate.startUpdate()
Start a batch row insertion/update. No changes are committed until the client commits the batch operation via HClient.batchCommit(). The entire batch update can be abandoned by calling HClient.batchAbort(); Callers to this method are given a handle that corresponds to the row being changed. The handle must be supplied on subsequent put or delete calls. @param row Name of row to start update against. @return Row lockid.
