What's Wrong?

The test.table1 table has c1, c2, c3, c4, c5, c6, c7, c8 fields

Use Spark's DataFrame to get data and set the parameter doris.read.fields
var dataDF = spark.read.format("doris")
.option("doris.table.identifier", "test.table1")
.option("doris.fenodes", dorisHost + ":" + dorisHttpPort)
.option("doris.user", dorisUsername)
.option("doris.password", dorisPassword)
.option("doris.read.fields","c1,c2,c3,c4")
.option("doris.read.mode", "arrow")
.option("doris.read.arrow-flight-sql.port", dorisArrowPort)
.load()

The sql should be: SELECT c1,c2,c3,c4 FROM test.table1
But the query sql is: SELECT c1,c2,c3,c4,c5,c6,c7,c8 FROM test.table1

What You Expected?

Using Arrow Fillght SQL mode in DataFrame allows you to query the corresponding column data according to the doris.read.fields parameter instead of querying all columns in the table.
