> When I use hbck fix overlap, there is data in the region that doesn't belong to it.
> reproduction steps:
> 1、create t1 and set COMPACTION_ENABLED=false
>  2、put r001 r002 r003 r004
>  3、flush t1 and flush meta
>  4、 major_compact meta, and get new meta hfile1 
>  5、 split t1, r0022
>  6、 flush meta, and get new meta hfile2
>  7、 stop cluster，delet all WALs，, delete hfile2
>  8、 restart hbase
>  9、 split t1,r0022，and hdfs has 5 regions(1 parent, 2 old daughter, 2 new daughter), meta has 3 region(1 parent, 2 new daughter)
>  10、use hbck to repair until t1 is healthy
> the result： 514476289cd49db63ab7ef27e944185b has no data.
