> hive read mor rt table, will get duplicated record in below case:
> # using bucket index type
> # say primary key 1 - 100, set bucket number to 1
> # insert 1 - 100 record ,compact it , one parquet file will be generated
> # insert 1 - 100 record once again, but dont't compact it, so the data file
> will contain 1 parquet file + 1 log file.
> # select * from table where key=1, you will get 2 record.
> the cause is :
> in HoodieMergeOnReadtableInputFormat ,the isSplitable will return true, it
> will generate two map task, each task include the log file, so each task
> will return one record.
