Examples with DelimitedRecordFormat org.apache.storm.hdfs.bolt.format.DelimitedRecordFormat used on opensource projects

Example 1 with DelimitedRecordFormat

use of org.apache.storm.hdfs.bolt.format.DelimitedRecordFormat in project storm by apache.

the class TestHdfsBolt method makeHdfsBolt.

private HdfsBolt makeHdfsBolt(String nameNodeAddr, int countSync, float rotationSizeMB) {
    RecordFormat fieldsFormat = new DelimitedRecordFormat().withFieldDelimiter("|");
    SyncPolicy fieldsSyncPolicy = new CountSyncPolicy(countSync);
    FileRotationPolicy fieldsRotationPolicy = new FileSizeRotationPolicy(rotationSizeMB, FileSizeRotationPolicy.Units.MB);
    FileNameFormat fieldsFileNameFormat = new DefaultFileNameFormat().withPath(testRoot);
    return new HdfsBolt().withFsUrl(nameNodeAddr).withFileNameFormat(fieldsFileNameFormat).withRecordFormat(fieldsFormat).withRotationPolicy(fieldsRotationPolicy).withSyncPolicy(fieldsSyncPolicy);
}

Example 2 with DelimitedRecordFormat
