Key: HADOOP-3356
URL: https://issues.apache.org/jira/browse/HADOOP-3356
Project: Hadoop Core
Issue Type: Bug
Components: io
Affects Versions: 0.16.3
Reporter: Arun C Murthy
Assignee: Arun C Murthy
Fix For: 0.18.0
The offending code is:
{code:title=SequenceFile.java}
Path outputFile = lDirAlloc.getLocalPathForWrite(
tmpFilename.toString(),
approxOutputSize, conf);
LOG.debug("writing intermediate results to " + outputFile);
Writer writer = cloneFileAttributes(
fs.makeQualified(segmentsToMerge.get(0).segmentPathName),
fs.makeQualified(outputFile), null);
{code}
*fs* is InMemoryFileSystem when ReduceTask.ReduceCopier constructs it... so the wrong FileSystem is used during intermediate merges.
