[jira] [Created] (MAPREDUCE-2571) CombineFileInputFormat.getSplits
throws a java.lang.ArrayStoreException
CombineFileInputFormat.getSplits throws a java.lang.ArrayStoreException
-----------------------------------------------------------------------
Key: MAPREDUCE-2571
URL: https://issues.apache.org/jira/browse/MAPREDUCE-2571
Project: Hadoop Map/Reduce
Issue Type: Bug
Affects Versions: 0.21.0
Reporter: Bochun Bai
Priority: Blocker
The getSplits methods of
org.apache.hadoop.mapred.lib.CombineFileInputFormat
not work.
...mapred.lib.CombineFileInputFormat(0.20-style) is a proxy for ...mapreduce.lib.input.CombineFileInputFormat(0.21-style)
The 0.21-style getSplits returns ArrayList<...mapreduce.lib.input.CombineFileSplit>
and the 0.20-style delegation calls toArray(...mapred.InputSplit[])
The ...mapreduce.lib.input.CombineFileSplit is based on ...mapreduce.InputSplit
and ...mapred.InputSplit is a interface, not a super-class of ...mapreduce.InputSplit
