-----------------------------------
Summary: Append SequenceFile with
compressionType(NONE,RECORD,BLOCK) throws NullPointerException
Key: HADOOP-13216
URL: https://issues.apache.org/jira/browse/HADOOP-13216
Project: Hadoop Common
Issue Type: Bug
Components: fs
Affects Versions: 2.7.2
Reporter: Syed Akram
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.
