> File descriptor leaks are observed coming from the JobHistoryServer process
> while it tries to render a "corrupted" aggregated log on the JHS Web UI.
> Issue reproduced using the following steps:
> # Ran a sample Hadoop MR Pi job, it had the id -
> application_1582676649923_0026.
> # Copied an aggregated log file from HDFS to local FS:
> {code}
> hdfs dfs -get
> /tmp/logs/systest/logs/application_1582676649923_0026/<nm_hostname>_8041
> {code}
> # Updated the TFile metadata at the bottom of this file with some junk to
> corrupt the file :
