--------------------------------
Summary: Move block files to container directory after the first
put block
Key: HDDS-8117
URL: https://issues.apache.org/jira/browse/HDDS-8117
Project: Apache Ozone
Issue Type: Sub-task
Reporter: Ritesh Shukla
If there is a failure in the write chunk requests before the first put block, a
file will be left in the container directory that has no corresponding RocksDB
entry. This isn't really a bug because the data is unreferenced, but it would
be good to have the container directory only contain block files with committed
data.
The proposal is to initially write the block file to a tmp directory, and use
atomic filesystem mv to put it in the container directory on the first put
block request. Subsequent writes to the block will use the block file in the
container.
