- when no block size is provided and there's not a preread headerBuf, treat the value with caution.
- verify HBase checksums before making use of the block header.
- inline verifyOnDiskSizeMatchesHeader to keep throw/return logic in the method body.
- separate validation of onDiskSizeWithHeader as input parameter from as read from block header
- simplify branching around fetching and populating onDiskSizeWithHeader.
- inline retrieving nextOnDiskBlockSize ; add basic validation.
- whenever a read is determined to be corrupt and fallback to HDFS checksum is necessary, also invalidate the cached value of headerBuf.
- build out a test suite covering various forms of block header corruption, for blocks in first and second positions.
