--------------------------------
Summary: sensitive inform may leak due to crash
Key: MAPREDUCE-7382
URL: https://issues.apache.org/jira/browse/MAPREDUCE-7382
Project: Hadoop Map/Reduce
Issue Type: Bug
Reporter: lujie
current, we implement processDoneFiles in JobHistoryEventHandler like:
{code:java}
// try {
String doneSummaryFileName = getTempFileName(JobHistoryUtils
.getIntermediateSummaryFileName(jobId));
qualifiedSummaryDoneFile = doneDirFS.makeQualified(new Path(
doneDirPrefixPath, doneSummaryFileName));
summaryFileOut = doneDirFS.create(qualifiedSummaryDoneFile, true);
summaryFileOut.writeUTF(mi.getJobSummary().getJobSummaryString());
summaryFileOut.close();
doneDirFS.setPermission(qualifiedSummaryDoneFile, new FsPermission(
JobHistoryUtils.HISTORY_INTERMEDIATE_FILE_PERMISSIONS));
} catch (IOException e) {
LOG.info("Unable to write out JobSummaryInfo to ["
+ qualifiedSummaryDoneFile + "]", e);
throw e;
} {code}
wihle node crash before setPermission, we may leak SummaryDoneFile.
code should be like:
{code:java}
try {
String doneSummaryFileName = getTempFileName(JobHistoryUtils
.getIntermediateSummaryFileName(jobId));
qualifiedSummaryDoneFile = doneDirFS.makeQualified(new Path(
doneDirPrefixPath, doneSummaryFileName));
summaryFileOut = doneDirFS.create(qualifiedSummaryDoneFile, true);
doneDirFS.setPermission(qualifiedSummaryDoneFile, new FsPermission(
JobHistoryUtils.HISTORY_INTERMEDIATE_FILE_PERMISSIONS));
summaryFileOut.writeUTF(mi.getJobSummary().getJobSummaryString());
summaryFileOut.close();
} catch (IOException e) {
LOG.info("Unable to write out JobSummaryInfo to ["
+ qualifiedSummaryDoneFile + "]", e);
{code}
