     | Property | Default Value | Description |
     
|----------------------------|-------------------------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
    -| carbon.storelocation | /user/hive/warehouse/carbon.store | Location 
where CarbonData will create the store, and write the data in its own format. 
NOTE: Store location should be in HDFS. |
    -| carbon.ddl.base.hdfs.url | hdfs://hacluster/opt/data | This property is 
used to configure the HDFS relative path, the path configured in 
carbon.ddl.base.hdfs.url will be appended to the HDFS path configured in 
fs.defaultFS. If this path is configured, then user need not pass the complete 
path while dataload. For example: If absolute path of the csv file is 
hdfs://10.18.101.155:54310/data/cnbc/2016/xyz.csv, the path 
"hdfs://10.18.101.155:54310" will come from property fs.defaultFS and user can 
configure the /data/cnbc/ as carbon.ddl.base.hdfs.url. Now while dataload user 
can specify the csv path as /2016/xyz.csv. |
    -| carbon.badRecords.location | /opt/Carbon/Spark/badrecords | Path where 
the bad records are stored. |
    -| carbon.data.file.version | 3 | If this parameter value is set to 1, then 
CarbonData will support the data load which is in old format(0.x version). If 
the value is set to 2(1.x onwards version), then CarbonData will support the 
data load of new format only. The default value for this parameter is 3(latest 
version is set as default version). It improves the query performance by ~20% 
to 50%. For configuring V3 format explicitly, add carbon.data.file.version = V3 
in carbon.properties file. |
    +| carbon.storelocation |  | Location where CarbonData will create the 
store, and write the data in its own format. NOTE: Store location should be in 
HDFS. |
