IMHO, the changes for HBASE-17863 are > unlikely to affect get/ put path. > I ran the test with and without the patch several times locally and found > that TestAcidGuarantees fails without the patch similar number of times. > Opening blocker, considering acid guarantees are critical to HBase. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
