From here on down, we have a bunch of defines and specific CELL_GRID of Cells. The CELL_GRID then has a Scanner that can fake out 'block' transitions. All this elaborate setup is for tests that ensure we don't overread, and that the StoreScanner is not overly enthusiastic.

CELL_GRID

private static final org.apache.hadoop.hbase.Cell[] CELL_GRID

Five rows by four columns distinguished by column qualifier (column qualifier is one of the four rows... ONE, TWO, etc.). Exceptions are a weird row after TWO; it is TWO_POINT_TWO. And then row FOUR has five columns finishing w/ row FIVE having a single column. We will use this to test scan does the right thing as it we do Gets, StoreScanner#optimize, and what we do on (faked) block boundaries.

Method Details

testWithColumnCountGetFilter

public void testWithColumnCountGetFilter()
                                  throws Exception

Throws:

Exception

getCols

NavigableSet<byte[]> getCols(String... strCols)

testFullRowGetDoesNotOverreadWhenRowInsideOneBlock

public void testFullRowGetDoesNotOverreadWhenRowInsideOneBlock()
                                                        throws IOException

Throws:

IOException

testFullRowSpansBlocks

public void testFullRowSpansBlocks()
                            throws IOException

Throws:

IOException

testOptimize

public void testOptimize()
                  throws IOException

Test optimize in StoreScanner. Test that we skip to the next 'block' when we it makes sense reading the block 'index'.

Throws:

IOException

testOptimizeAndGet

public void testOptimizeAndGet()
                        throws IOException

Ensure the optimize Scan method in StoreScanner does not get in the way of a Get doing minimum work... seeking to start of block and then SKIPPING until we find the wanted Cell. This 'simple' scenario mimics case of all Cells fitting inside a single HFileBlock. See HBASE-15392. This test is a little cryptic. Takes a bit of staring to figure what it up to.

Throws:

IOException

testOptimizeAndGetWithFakedNextBlockIndexStart

public void testOptimizeAndGetWithFakedNextBlockIndexStart()
                                                    throws IOException

Ensure that optimize does not cause the Get to do more seeking than required. Optimize (see HBASE-15392) was causing us to seek all Cells in a block when a Get Scan if the next block index/start key was a different row to the current one. A bug. We'd call next too often because we had to exhaust all Cells in the current row making us load the next block just to discard what we read there. This test is a little cryptic. Takes a bit of staring to figure what it up to.

IOException
