[jira] [Created] (HADOOP-8531) SequenceFile Writer can throw out a
better error if a serializer isn't available
Harsh J created HADOOP-8531:
-------------------------------
Summary: SequenceFile Writer can throw out a better error if a serializer isn't available
Key: HADOOP-8531
URL: https://issues.apache.org/jira/browse/HADOOP-8531
Project: Hadoop Common
Issue Type: Improvement
Reporter: Harsh J
Priority: Trivial
Currently, if the provided Key/Value class lacks a proper serializer in the loaded config for the SequenceFile.Writer, we get an NPE as the null return goes unchecked.
Hence we get:
{code}
java.lang.NullPointerException
at org.apache.hadoop.io.SequenceFile$Writer.init(SequenceFile.java:1163)
at org.apache.hadoop.io.SequenceFile$Writer.<init>(SequenceFile.java:1079)
at org.apache.hadoop.io.SequenceFile$RecordCompressWriter.<init>(SequenceFile.java:1331)
at org.apache.hadoop.io.SequenceFile.createWriter(SequenceFile.java:271)
{code}
We can provide a better message + exception in such cases. This is slightly related to MAPREDUCE-2584.
