in hbase 0.98.10, class HRegion, line 1277 to 1286: there are two methods: "getStoreOpenAndCloseThread" and "getStoreFileOpenAndCloseThreadPool", getStoreOpenAndCloseThread is to get the thread pool size for open/close Stores, and getStoreFileOpenAndCloseThreadPool is used to get pool size for open/close storeFiles, but they use the same conf: "HSTORE_OPEN_AND_CLOSE_THREADS_MAX".
there shoud be no relation with store number and storeFile number, so we should use different conf for two methods
