Subject [jira] [Created] (HDFS-6934) Move checksum computation off the hot path when writing to RAM disk
Date Sat, 23 Aug 2014 21:36:11 GMT
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.
            Reporter: Arpit Agarwal
