> 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, 2.6.0, 3.0.0-alpha-3, 2.4.13
>
>
> 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.
