Jianwei Cui created HBASE-15497: ----------------------------------- Summary: Incorrect javadoc for atomicity guarantee of Increment and Append Key: HBASE-15497 URL: https://issues.apache.org/jira/browse/HBASE-15497 Project: HBase Issue Type: Bug Components: documentation Affects Versions: 2.0.0 Reporter: Jianwei Cui Priority: Minor
At the front of {{Increment.java}} file, there is comment about read atomicity: {code} * This operation does not appear atomic to readers. Increments are done * under a single row lock, so write operations to a row are synchronized, but * readers do not take row locks so get and scan operations can see this * operation partially completed. {code} It seems this comment is not true after MVCC integrated [HBASE-4583|https://issues.apache.org/jira/browse/HBASE-4583]. Currently, the readers can be guaranteed to read the whole result of Increment if I am not wrong. Similar comments also exist in {{Append.java}}, {{Table#append(...)}} and {{Table#increment(...)}} -- This message was sent by Atlassian JIRA (v6.3.4#6332)
