Konstantin Shvachko created HDFS-4308:
-----------------------------------------
Summary: addBlock() should persist file blocks once
Key: HDFS-4308
URL: https://issues.apache.org/jira/browse/HDFS-4308
Project: Hadoop HDFS
Issue Type: Bug
Components: namenode
Affects Versions: 2.0.3-alpha
Reporter: Konstantin Shvachko
FSNamesystem.getAdditionalBlock() persists all file blocks twice, first in
{{dir.removeBlock()}} using OP_ADD, then immediately after that in
{{dir.persistBlocks()}} using OP_UPDATE_BLOCKS.
This should be aggregated in one call to logEdit().
