That's why all my tests where done only once 100% of the data was in whatever cache I was using (block cache or OS buffer). > Re-enable hbase checksums by default > ------------------------------------ > > Key: HBASE-8322 > URL: https://issues.apache.org/jira/browse/HBASE-8322 > Project: HBase > Issue Type: Improvement > Components: Filesystem Integration > Reporter: Enis Soztutar > Assignee: Enis Soztutar > Fix For: 0.98.0, 0.95.1 > > Attachments: hbase-8322_v1.patch > > > Double checksumming issues in HBase level checksums(HBASE-5074) has been fixed in HBASE-6868. However, that patch also disables hbase checksums by default. I think we should re-enable it by default, and document the interaction with shortcircuit reads. -- This message is automatically generated by JIRA.
