--------------------------------------------
Summary: NullPointerException while closing CQLSSTableWriter
Key: CASSANDRA-13670
URL: https://issues.apache.org/jira/browse/CASSANDRA-13670
Project: Cassandra
Issue Type: Bug
Components: Tools
Environment: Linux
Reporter: Arpan Khandelwal
Fix For: 3.0.14
Reading data from csv file and writing using CQLSSTableWriter. If I use
writer.addRow(); instead of using writer.rawAddRow() it works fine.
{code:java}
CQLSSTableWriter.Builder builder = CQLSSTableWriter.builder();
builder.inDirectory(outputDir).forTable(createDDL).using(insertDML).withPartitioner(new
Murmur3Partitioner());
CQLSSTableWriter writer = builder.build();
{code}
{code:java}
try (BufferedReader reader = new BufferedReader(new FileReader(csvFilePath));
CsvListReader csvReader = new CsvListReader(reader,
CsvPreference.STANDARD_PREFERENCE);) {
List<String> line;
while ((line = csvReader.read()) != null) {
List<ByteBuffer> bbl = new ArrayList<>();
for (String l : line) {
bbl.add(ByteBuffer.wrap(l.getBytes()));
}
writer.rawAddRow(bbl);
// If I use writer.addRow(); it works fine.
}
} finally {
writer.close();
}
{code}
{code:java}
