> while Appending sequenceFile with any Compression Type (NONE, RECORD, BLOCK),
> getting writer
> SequenceFile.createWriter(conf,
> SequenceFile.Writer.file(path),
> SequenceFile.Writer.compression(ctype),
> SequenceFile.Writer.keyClass(Key.class),
> SequenceFile.Writer.valueClass(value..class),
> SequenceFile.Writer.appendIfExists(true),
> );
> Above throws the below exception when we try to append existing sequencefile
> with some compression technique,
> java.lang.NullPointerException
> at
> org.apache.hadoop.io.SequenceFile$Writer.<init>(SequenceFile.java:1118)
> at org.apache.hadoop.io.SequenceFile.createWriter(SequenceFile.java:273)
> at SequenceFileTest.getWriter(SequenceFileTest.java:342)
> at SequenceFileTest.writeContent(SequenceFileTest.java:429)
> at SequenceFileTest.<init>(SequenceFileTest.java:83)
> at SequenceFileTest.main(SequenceFileTest.java:565)
> If i use below writer
> SequenceFile.createWriter(conf,
> SequenceFile.Writer.file(path),
> SequenceFile.Writer.keyClass(keyClass),
> SequenceFile.Writer.valueClass(keyClass),
> SequenceFile.Writer.appendIfExists(append)
> );
> without any compressiontype, then it works fine.
