Arpit Agarwal updated HDFS-5704:
--------------------------------
Environment: (was: Currently every time a block a allocated, the entire
list of blocks are written in the editlog in OP_UPDATE_BLOCKS operation. This
has n^2 growth issue. The total size of editlog records for a file with large
number of blocks could be huge.
The goal of this jira is discuss adding a different editlog record that only
records allocation of block and not the entire block list, on every block
allocation.)
> Change OP_UPDATE_BLOCKS with a new OP_ADD_BLOCK
