LuceneDocumentWrapper Needs no argument constructor
---------------------------------------------------
Key: HBASE-2532
URL: https://issues.apache.org/jira/browse/HBASE-2532
Project: Hadoop HBase
Issue Type: Bug
Components: mapreduce
Affects Versions: 0.20.3
Environment: All
Reporter: Ananth Sarathy
For reading an object out a sequencefile, a no argument constructor is
required...
if not you end up with a java.lang.NoSuchMethodException
>From Owen O'Malley
Assumption for Writables that should be documented somewhere:
* Each type must have a 0 argument constructor.
* Each call to write must not assume any shared state.
* Each call to readFields must consume exactly the number of bytes
produced by write.
SequenceFile also assumes:
* All keys are exactly the same type (not polymorphic).
* All values are exactly the same type.
* Both types are specified by the writer in the create call.
