> Currently, in HBaseFsck#checkRegionBoundaries(), it seems like keys from reader.getFirstKey()
and reader.getLastKey() are directly compared by ByteArrayComparator:
> https://github.com/apache/hbase/blob/9d0c7c6dfbcba0907cbbc2244eac570fcc4d58a5/hbase-server/src/main/java/org/apache/hadoop/hbase/util/HBaseFsck.java#L864-L865

> This is not correct because the keys consist of a key length and key itself. We should
compare rowkeys or the only key itself (by removing a key length).
