------------------------------

             Summary: The IndexChunkPool’s percentage is hard code to 0.1
                 Key: HBASE-23196
                 URL: https://issues.apache.org/jira/browse/HBASE-23196
             Project: HBase
          Issue Type: Bug
            Reporter: chenxu


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.
