Pallavi Singh created CARBONDATA-578:
----------------------------------------
Summary: CarbonData V2 Format Default Behavior
Key: CARBONDATA-578
URL: https://issues.apache.org/jira/browse/CARBONDATA-578
Project: CarbonData
Issue Type: Bug
Reporter: Pallavi Singh
Priority: Minor
In the CarbonCommonConstants.java it has been specified :
public static final String CARBON_DATA_FILE_DEFAULT_VERSION = "V2";
as default. Then why in CarbonDataReaderFactory.java
public DimensionColumnChunkReader
getDimensionColumnChunkReader(ColumnarFormatVersion version,
BlockletInfo blockletInfo, int[] eachColumnValueSize, String filePath) {
switch (version) {
case V2:
return new CompressedDimensionChunkFileBasedReaderV2(blockletInfo,
eachColumnValueSize,
filePath);
case V1:
return new CompressedDimensionChunkFileBasedReaderV1(blockletInfo,
eachColumnValueSize,
filePath);
default:
throw new IllegalArgumentException("invalid format version: " +
version);
}
}
throw an exception for Invalid format, when default Format Version is V2.
By default it should take V2 as default format.
