thx Ravindra.
I've run the script as:
scala> import org.apache.carbondata.core.util.CarbonProperties
scala>
CarbonProperties.getInstance().addProperty("carbon.badRecords.location","hdfs://master:9000/data/carbondata/badrecords/")
scala> val carbon =
SparkSession.builder().config(sc.getConf).getOrCreateCarbonSession("hdfs://master:9000/opt/carbonStore")
scala> carbon.sql(s"load data inpath '$src/web_sales.csv' into table
_1g.web_sales
OPTIONS('DELIMITER'='|','bad_records_logger_enable'='true','use_kettle'='true')")
but it occured an Exception: java.lang.RuntimeException: carbon.kettle.home is
not set
the configuration in my carbon.properties is:
carbon.kettle.home=/opt/spark-2.1.0/carbonlib/carbonplugins, but it seems not
work.
how can I solve this problem.

Hi Liang Chen,
would you add a more detail document about the badRecord shows us how to
use it, thx~~

Hi,
I guess you are using spark-shell, so better set bad record location to
CarbonProperties class before creating carbon session like below.
CarbonProperties.getInstance().addProperty("carbon.badRecords.location","<bad
record location>").
1. And while loading data you need to enable bad record logging as below.
carbon.sql(s"load data inpath '$src/web_sales.csv' into table _1g.web_sales
OPTIONS('DELIMITER'='|','bad_records_logger_enable'='true', 'use_kettle
'='true')").
Please check the bad records which are added to that bad record location.
2. You can alternatively verify by ignoring the bad records by using
following command
carbon.sql(s"load data inpath '$src/web_sales.csv' into table _1g.web_sales
OPTIONS('DELIMITER'='|','bad_records_logger_enable'='true',
'bad_records_action'='ignore')").
Regards,
Ravindra.
