A BlockECReconstructionCommand (shorthand for Block Erasure Coding Reconstruction) is an instruction to a DataNode to reconstruct a striped block group with missing blocks.
Upon receiving this command, the DataNode pulls data from other hosting blocks in this group and reconstructs the lost blocks through calculation.
Implementation details will be added later.
