我有以下数据：
"ElemUID ElemName Kind Number DaySecFrom(UTC) DaySecTo(UTC)"
"399126817 A648/13FKO-66 DEZ 2017-07-01 23:58:00.000 2017-07-01 23:59:00.000"

"399126818 A648/12FKO-1 DEZ 180.00 2017-07-01 23:58:00.000 2017-07-01 23:59:00.000"
"399126816 A648/13FKO-65 DEZ 2017-07-01 23:58:00.000 2017-07-01 23:59:00.000"

我把它加载到HDFS。然后我在Hive中定义了一个外部表：
CREATE EXTERNAL TABLE IF NOT EXISTS deg
(
ElemUID int,
ElemName string,
Kind string,
Number float,
timefromdeg string,
timetodeg string
)
ROW FORMAT DELIMITED
FIELDS TERMINATED BY '\t'
LINES TERMINATED BY '\n'
TBLPROPERTIES ("skip.header.line.count"="1");
然后我用LOAD DATA INPATH..将数据集加载到定义的模式中
现在我希望它用tbl()加载到sparklyr。每次我这样做，我总是把标题作为第一行中的数据：
输出glimpse()：
Variables: 6
$ elemuid <int> NA, 399126817, 483492732, 399126819, 399126818, 399126816, 39...
$ elemname <chr> "ElemName", "A648/13FKO-66", "A661/18FRS-97", "A648/12FKO-2",...
$ kind <chr> "Kind", "DEZ", "DEZ", "DEZ", "DEZ", "DEZ", "DEZ", "DEZ", "DEZ...
$ number <dbl> NaN, NaN, 120, 60, 180, NaN, 120, NaN, NaN, 60, 180, NaN, NaN...
$ timefrom <dttm> NA, 2017-07-01 23:58:00, 2017-07-01 23:58:00, 2017-07-01 23:...
$ timeto <dttm> NA, 2017-07-01 23:59:00, 2017-07-01 23:59:00, 2017-07-01 23:...
我觉得这会扰乱我后来的分析。在创建外部table()时，我已使用TBLPROPERTIES ("skip.header.line.count"="1")
是否有可能跳过sparklyr中的第一行？
谢谢！
