> Key: HBASE-23196
> URL: https://issues.apache.org/jira/browse/HBASE-23196
> Project: HBase
> Issue Type: Bug
> Affects Versions: 2.0.0
> Reporter: chenxu
> Assignee: chenxu
> Priority: Major
>
> Code in ChunkCreator#initialize
> {code:java}
> public static ChunkCreator initialize(...) {
> if (instance != null) {
> return instance;
> }
> instance = new ChunkCreator(chunkSize, offheap, globalMemStoreSize,
> poolSizePercentage,
> initialCountPercentage, heapMemoryManager,
> MemStoreLABImpl.INDEX_CHUNK_PERCENTAGE_DEFAULT);
> return instance;
> }
> {code}
> When mslab is enabled, the IndexChunkPool’s percentage is hard code to
> INDEX_CHUNK_PERCENTAGE_DEFAULT, When we use IndexType#ARRAY_MAP other than
> IndexType#CHUNK_MAP, we should set IndexChunkPool’s size to 0, or there will
> be a waste of memory space.
