```
if (overwrite && !insertCommand.dynamicPartitionOverwrite) {
DDLUtils.verifyNotReadPath(actualQuery, outputPath)
}
```
DynamicPartitionOverwrite does not delete data before job begin, so it will
not encountered verify problem.
Since we use directly outputCommitter to write files. For the case `Insert
overwrite static partition from data read from same table's partition`, we just
tune `insertCommand.dynamicPartitionOverwrite` to true to avoid delete
partition data before read.
