>
> Currently, one has to specify the data block encoding of the table explicitly
> using the config parameter
> "hbase.mapreduce.hfileoutputformat.datablock.encoding" when doing a bulkload
> load. This option is easily missed, not documented and also works differently
> than compression, block size and bloom filter type, which are auto detected.
> The solution would be to add support to auto detect datablock encoding
> similar to other parameters.
> The current patch does the following:
> 1. Automatically detects datablock encoding in HFileOutputFormat.
> 2. Keeps the legacy option of manually specifying the datablock encoding
> around as a method to override auto detections.
> 3. Moves string conf parsing to the start of the program so that it fails
> fast during starting up instead of failing during record writes. It also
> makes the internals of the program type safe.
> 4. Adds missing doc strings and unit tests for code serializing and
> deserializing config paramerters for bloom filer type, block size and
> datablock encoding.
