Chetan Khatri updated HBASE-17547:
----------------------------------
Description:
Issue: HBase-Spark Module : TableCatelog doesn't supports multiple columns from
single column family.
Description:
Datasource API under HBase-Spark Module having error, which accessing more than
1 columns from same column family.
If your catalog having the format where you have multiple columns from single /
multiple column family, at that point it throws an exception, for example.
def empcatalog = s"""{
|"table":{"namespace":"empschema", "name":"emp"},
|"rowkey":"key",
|"columns":{
|"empNumber":{"cf":"rowkey", "col":"key", "type":"string"},
|"city":{"cf":"pdata", "col":"city", "type":"string"},
|"empName":{"cf":"pdata", "col":"name", "type":"string"},
|"jobDesignation":{"cf":"pdata", "col":"designation", "type":"string"},
|"salary":{"cf":"pdata", "col":"salary", "type":"string"}
|}
|}""".stripMargin
Here, we have city, name, designation, salary from pdata column family.
Exception while saving Dataframe at HBase.
java.lang.IllegalArgumentException: Family 'pdata' already exists so cannot be
added

HBaseTableCatalog.scala class has getColumnFamilies method which returns
duplicates, which should not return.
Unit test has been written for the same at DefaultSourceSuite.scala,
writeCatalog object definition.
