Zhihong Yu commented on HBASE-5864:
-----------------------------------
{code}
- DataInputStream nextBlockAsStream(BlockType blockType) throws IOException;
+ HFileBlock nextBlockAsStream(BlockType blockType) throws IOException;
{code}
The method should be named nextBlock() because stream isn't returned.
{code}
+ * Read in the root-level index from the given input stream. Must match
{code}
'input stream' is no longer the input. HFileBlock is.
Please add @return to the javadoc.
For TestHFileWriterV2.java:
{code}
- final Compression.Algorithm COMPRESS_ALGO = Compression.Algorithm.GZ;
+ final Compression.Algorithm COMPRESS_ALGO = Compression.Algorithm.NONE;
{code}
We should exercise both compression algorithms. Refactoring is needed.
