-------------------------------------
Summary: Change OP_UPDATE_BLOCKS with a new OP_ADD_BLOCK
Key: HDFS-5704
URL: https://issues.apache.org/jira/browse/HDFS-5704
Project: Hadoop HDFS
Issue Type: Bug
Environment: 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.
