-------------------------------------
Summary: Memory leak for HistoryFileManager.getJobSummary()
Key: MAPREDUCE-6528
URL: https://issues.apache.org/jira/browse/MAPREDUCE-6528
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: jobhistoryserver
Reporter: Junping Du
Assignee: Junping Du
Priority: Critical
We meet memory leak issues for JHS in a large cluster which is caused by code
below doesn't release FSDataInputStream in exception case. MAPREDUCE-6273
should fix most cases that exceptions get thrown. However, we still need to fix
the memory leak for occasional case.
{code}
private String getJobSummary(FileContext fc, Path path) throws IOException {
Path qPath = fc.makeQualified(path);
FSDataInputStream in = fc.open(qPath);
String jobSummaryString = in.readUTF();
in.close();
return jobSummaryString;
}
{code}
