adoroszlai opened a new pull request #141: HDDS-2458. Avoid list copy in ChecksumData URL: https://github.com/apache/hadoop-ozone/pull/141 ## What changes were proposed in this pull request? Create `ChecksumData` with checksum list, instead of updating it right after creation, to avoid unnecessarily copying the list. https://issues.apache.org/jira/browse/HDDS-2458 ## How was this patch tested? Tested on 3-node cluster with a 120MB key. `ozone sh key get` verifies the checksum. ``` ozone freon ockg -p test -t 1 -n 1 # easy volume and bucket creation ;) cat share/ozone/lib/*jar > tmp.jar ozone sh key put vol1/bucket1/test/large tmp.jar ozone sh key get vol1/bucket1/test/large tmp.jar.out diff -q tmp.jar tmp.jar.out ```
