Method Details

testMultiIndexLevelRandomHFileWithBlooms

public void testMultiIndexLevelRandomHFileWithBlooms()
                                              throws IOException

Scanner.seekBefore() could fail because when seeking to a previous HFile data block, it needs to know the size of that data block, which it calculates using current data block offset and the previous data block offset. This fails to work when there are leaf-level index blocks in the scannable section of the HFile, i.e. starting in HFileV2. This test will try seekBefore() on a flat (single-level) and multi-level (2,3) HFile and confirm this bug is now fixed. This bug also happens for inline Bloom blocks for the same reasons.

Throws:

IOException

Throws:

Throws:
