There is indeed. As of 1.4, maybe earlier there is a class called MultiTableBatchWriter.
I believe the usage is as follows.
One obtains one via calling:
MultiTableBatchWriter mtbw = conn.createMultiTableBatchWriter(long maxMemory, long maxLatency, int maxWriteThreads)
on a Connector object.
Then obtain BatchWriters for your various tables
BatchWriter bw1 = mtbw.getBatchWriter("table1");
BatchWriter bw2 = mtbw.getBatchWriter("table2");
When done, one closes the MultiTableBatchWriter
