Duo Zhang commented on HBASE-26856: ----------------------------------- Any updates here? It also makes TestMultiRespectsLimits fail on master branch. > BufferedDataBlockEncoder.OnheapDecodedCell value can get corrupted > ------------------------------------------------------------------ > > Key: HBASE-26856 > URL: https://issues.apache.org/jira/browse/HBASE-26856 > Project: HBase > Issue Type: Bug > Reporter: Mohammad Arshad > Assignee: Mohammad Arshad > Priority: Major > Fix For: 2.5.0, 3.0.0-alpha-3 > > > In our production cluster we observed the cell value is modified after > successful scanner read. After analyzing we observed OnheapDecodedCell is not > created properly. > We create OnheapDecodedCell with complete valAndTagsBuffer underlying array. > {code:java} > return new OnheapDecodedCell(Bytes.copy(keyBuffer, 0, this.keyLength), > currentKey.getRowLength(), currentKey.getFamilyOffset(), > currentKey.getFamilyLength(), > currentKey.getQualifierOffset(), currentKey.getQualifierLength(), > currentKey.getTimestamp(), currentKey.getTypeByte(), > valAndTagsBuffer.array(), > valAndTagsBuffer.arrayOffset() + vOffset, this.valueLength, > memstoreTS, tagsArray, > tOffset, this.tagsLength); > {code} > Here we are passing valAndTagsBuffer.array() for value extraction. > The underlying array will be modified if it is altered anywhere. -- This message was sent by Atlassian Jira (v8.20.7#820007)
