InterruptedException

testAfterPartialFlush

public void testAfterPartialFlush()
                           throws IOException,
SecurityException,
IllegalArgumentException

Test that we recover correctly when there is a failure in between the flushes. i.e. Some stores got flushed but others did not. Unfortunately, there is no easy hook to flush at a store level. The way we get around this is by flushing at the region level, and then deleting the recently flushed store file for one of the Stores. This would put us back in the situation where all but that store got flushed and the region died. We restart Region again, and verify that the edits were replayed.

Throws:

IOException

SecurityException

IllegalArgumentException

testAfterAbortingFlush

public void testAfterAbortingFlush()
                            throws IOException

Test that we could recover the data correctly after aborting flush. In the test, first we abort flush after writing some data, then writing more data and flush again, at last verify the data.

Throws:

IOException
