>                 URL: https://issues.apache.org/jira/browse/HBASE-23196
>             Project: HBase
>          Issue Type: Bug
>    Affects Versions: 2.0.0
>            Reporter: 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.
