/**
* Test a case when an inline index chunk is converted to a root one. This reproduces the bug in
* HBASE-6871. We write a carefully selected number of relatively large keys so that we accumulate
* a leaf index chunk that only goes over the configured index chunk size after adding the last
* key/value. The bug is in that when we close the file, we convert that inline (leaf-level) chunk
* into a root chunk, but then look at the size of that root chunk, find that it is greater than
* the configured chunk size, and split it into a number of intermediate index blocks that should
* really be leaf-level blocks. If more keys were added, we would flush the leaf-level block, add
* another entry to the root-level block, and that would prevent us from upgrading the leaf-level
* chunk to the root chunk, thus not triggering the bug.
