> insert overwrite ta partition(part=xxxx) select xxx from tb join ta where
> part=xxxx
> It seems like the Shared conflicts with the Exclusive lock for Insert
> Overwrite even though both are part of the same txn.
> More precisely insert overwrite requires X lock on partition and the read
> side needs an S lock on the query.
> A simpler case is
> insert overwrite ta partition(part=xxxx) select * from ta
