Chia-Ping Tsai updated HBASE-18752:
    Attachment: HBASE-18752.v0.patch

# remove the TimeRangeTracker from StoreFileWriterBuilder. There is no use case in our core
# add a test to check the TimeRange of HStoreFile. see TestHStore#testTimeRangeIfSomeCellsAreDroppedInFlush

> We drop superfluous cells in flushing, hence the TimeRange from snapshot is inaccurate
for the storefile. We should recalculate the TimeRange for the storefile, but the side-effect
is the extra cost - we need to extract the timestamp from cell (ByteBufferCell).
