[jira] [Created] (HDFS-6934) Move checksum computation off the hot
path when writing to RAM disk
Arpit Agarwal created HDFS-6934:
-----------------------------------
Summary: Move checksum computation off the hot path when writing to RAM disk
Key: HDFS-6934
URL: https://issues.apache.org/jira/browse/HDFS-6934
Project: Hadoop HDFS
Issue Type: Sub-task
Environment: Since local RAM is considered reliable we can avoid writing checksums on the hot path when replicas are being written to a local RAM disk.
The checksum can be computed by the lazy writer when moving replicas to disk.
