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. -- This message was sent by Atlassian JIRA (v6.1.5#6160)
