Tsz-wo Sze commented on RATIS-979:
----------------------------------
block_xx_yy.meta contains only CRCs, which are for detecting data corruption.
By metadata in HDFS, we mean the file infos stored in the Namenode. One of the
infos is the block length -- How could the datanodes store the committed block
length consistently without Namenode/Ratis?
