zhuobin zheng created HBASE-27464: ------------------------------------- Summary: In memory compaction 'COMPACT' may cause data mass when add cell bigger than maxAlloc(default 256k) size. Key: HBASE-27464 URL: https://issues.apache.org/jira/browse/HBASE-27464 Project: HBase Issue Type: Bug Components: in-memory-compaction Reporter: zhuobin zheng Attachments: image-2022-11-04-15-46-21-645.png
When init 'CellChunkImmutableSegment' for 'COMPACT' action, we not force copy to current MSLab. When cell size bigger than maxAlloc, cell will stay in previous chunk which will recycle after segment replace, and we may read wrong data when these chunk reused by others. !image-2022-11-04-15-46-21-645.png! Timeline: # add a cell 'A' bigger than 256K # cell 'A' will copy to a chunk 'A' when first compact # cell 'A' will retain in chunk 'A' when second compact # chunk 'A' recycled after segment swap and close -- This message was sent by Atlassian Jira (v8.20.10#820010)
