Description

I am trying to submit a job with JDBC data sources and getting nullpointerexception because of below code:

File Path - \kylin\source-jdbc\src\main\java\org\apache\kylin\source\jdbc\JdbcHiveInputBase.java

method - createSqoopToFlatHiveStep

//code start

String partCol = null;

if (partitionDesc.isPartitioned())

{ partCol = partitionDesc.getPartitionDateColumn();//tablename.colname }

// code end

Fon non-partition cubes, the value of partCol will be always null and creating a exception in below method:

//code start

static String quoteIdentifier(String identifier, SourceDialect dialect) {
if (KylinConfig.getInstanceFromEnv().enableHiveDdlQuote()) {
String[] identifierArray = identifier.split("
.");

//code end
