Jing Zhao commented on HDFS-7617:
---------------------------------
Hi Hui, while applying an editlog for adding a striped block, the
"dataBlockNum" and "parityBlockNum" information can be retrieved from the EC
schema, which is associated with either the file itself or its parental
directory. Thus I do not think we need to serialize them in the editlog.
In the current code since the EC schema XAttr work is still in progress, we
simply use HdfsConstants.NUM_DATA_BLOCKS and HdfsConstants.NUM_PARITY_BLOCKS
for block allocation. Maybe later you can use this jira to update
FSEditLogLoader after corresponding code gets committed.
